MyHeritage WGS DNA test results - initial comparison to an uploaded kit

 In January, I mentioned that I had now tested with MyHeritage, rather than just uploading kits from other DNA companies to that site, since MyHeritage have now brought in "Whole Genome Sequencing" (WGS).  At the time, my kit was still in the processing stage, and I was looking forward to receiving the results, and the possibility of comparing them to my other kits there.

So this post is the beginning of any comparisons, looking at the new test compared to the upload I did, in November 2016, of the data from my FTDNA test.  

[Please note, this is just my personal exploration of the results I have - I don't keep up with the "bigger picture" of what's happening regarding genetic genealogy so, if you're looking for more detailed analysis and comments regarding the WGS test, I suggest reading the comparisons carried out by someone such as Roberta Estes, on her blog, "DNAeXplained – Genetic Genealogy". I also don't have a subscription to MyHeritage, which might affect the level of detail available for my kits.]  

One of my expectations of the new test was that there would be less matches than I have with the FTDNA kit. This was because, in order to compare kits from different companies, who might not all test exactly the same points in the DNA, MyHeritage uses a process of 'imputation'.  This process 'fills in' gaps in the sequences. Although imputation seems to be a common process used by all of the DNA companies, and is carried out in accordance with specific principles, it can potentially lead to cases where people are incorrectly identified as matches, when they shouldn't be (and possibly vice versa).  Looking at my "new match" notifications from MyHeritage in the past, I've often thought that could be the case, with many of the matches showing low levels of shared DNA.  Hence my expectation that the better coverage of the new test would discount these lower level matches.

But I was wrong!

When I first received my results, the new kit showed a total number of matches of 17019, whereas my FTDNA uploaded kit showed 16531. The totals as at the time of writing this (23/3/26) are 17328, and 16820 respectively.

It's currently not possible to download a list of all one's matches at MyHeritage, although that used to be possible. So I opted for a 'cut & paste' collection of the closest 2000 matches to each kit, and put those into two spreadsheets (and, yes, that did take a while.)  For both kits, this resulted in the lowest matches having a total shared DNA of around 19cM/20cM.

I then did a fairly simple comparison between the two spreadsheets, and discovered that almost half of the names in each spreadsheet did not appear in the other sheet:   

It is possible (and, I imagine, quite likely) that many of those who only appeared on one sheet do match the other kit but are beyond the first 2000 matches. I haven't specifically looked at many of the matches to check that yet, given the numbers of "No" matches involved. But, with my 'close' and 'extended' family only accounting for 17 of the matches, and the rest all being 'distant', I can imagine small changes in the levels of shared DNA could make quite a change to the order in which they appear on my match list.  

It was also obvious from those figures that there was something a bit 'odd' with the comparisons, since one would expect the same number of 'yes' matches in each sheet.  

The difference was caused by the fact that I had only compared names (since I expected there might be differences in the levels of shared DNA, so hadn't included that information in the comparison criteria, but didn't think to include other items, such as age, where the matches were from, or who manages the DNA, etc.)  

The reasons I identified for the difference included:
- five names that appeared twice in the MyH sheet, but only once in the FTDNA.
- three matches appeared twice in the FTDNA sheet, but only once in the MyH sheet.
- ten matches in the MyH sheet were only identified as "DNA kit", an increase of three from the number of such matches in the FTDNA sheet.  
- three 'private' matches in the FTDNA sheet did not appear in the MyH sheet.

At this point, I copied all the ''no" entries into one spreadsheet, and the "yes" entries into another, and physically aligned all the "yes" entries for the two kits, so that I could investigate how the shared DNA levels might have changed.  I took out all of the 'anomalous' entries identified above, leaving 1009 entries which appeared in both kits. 

[Note, I have also now re-run the comparison between the sheets, having concatenated "name", "age", "from", "managed by", "contact", and the "tree or not", items. Doing so identified just three entries that didn't match up correctly. Two of them were where there was one entry in the MyH sheet but two in the FTDNA sheet, and I had picked the wrong one to include. One of these would make no difference to the figures, the other would increase the number of kits that have gained one segment. The third entry was a mismatch between two kits labelled as "unknown" that I hadn't spotted. I don't like that sort of error so, in the following, I have removed that kit (leaving 1008 in both 'yes' lists), and also updated the other two entries with the correct matching details.  The new comparison also showed that I could have included some of the entries just identified as "DNA kit" in the following comparisons, since they can be matched up across the two kits. However, I haven't added them in, since none of them are particularly close matches, or make a noticeable difference to the figures/charts.]

To start with, I looked at the "no" spreadsheet and, for each kit, plotted the total DNA shared against the longest segment, just to give me an idea of the levels of sharing that didn't make it into the other kit list:  

  


As you can see, the majority of the kits seem to be where the total shared is between 20-30cM, and the longest segment is less than 20cM.  As I mentioned above, I suspect that many of these kits might be matching my other test, but the variations mean the matches appear in different orders and these just didn't appear in the first 2000 entries. 

However, there are some where the longest segment is over 30cM, or the total shared DNA is over 40cM, as well as the longest segment being over 20cM.  So I decided to check each of those, to see if they were matching the other kit, but beyond the first 2000 matches - only four of them were:

Of the four kits easily identified as also matching the other (FTDNA upload), the first in the table above had gained two new segments, on different chromosomes, the next had lost one segment, but then gained three new segments on other chromosomes, the third showed increases on the two 'existing' segments, plus the addition of a new segment on a different chromosome, and the final one showed an increase (of over 20cM) on the 'existing' segment.

I might come back to these details, as and when I take another look at chromosome mapping. But, for now, I moved on to look at the 'yes' sheet, ie those matches that appeared in the first 2000 entries of both my FTDNA upload, and also the new MyHeritage WGS test.

The 'yes' kits   

I began by looking at a scattergram of the change in 'Total cM shared' against the change in 'Longest segment' but it's perhaps more helpful to look at the following two charts first.

This shows the numbers of matches whose 'Total cM shared' changed, within particular ranges of values (calculated by 'Total shared cM with MyH kit - Total shared cM with FTDNA upload'):

 


From this, you can see that the Total cM shared, for the majority of matches, did not change by very much.  

I think that's important to note, given that the specific examples I'm exploring in more detail are all 'outliers', ie the matches where the changes are more extreme.  I'm looking at them because I find the situations intriguing, not because I'm saying there is anything 'wrong'.  

One can see the same thing, when looking at the changes in values of the 'Longest segment' (calculated by Longest segment matching MyH kit - Longest segment matching FTDNA upload) - the majority of matches showed very little change in the longest segment value:   


The following image shows the changes in Total cM shared against the changes in Longest segment for each individual match:


I think there are two different things showing up here - there's the points falling along a diagonal, indicating that there's been a change in both the Longest segment length and the Total cM shared. But then also a horizontal line of points along the x-axis, where there's been a change in Total cM shared, but without corresponding changes to the Longest segment length - potentially indicating the loss, or gain, of other, smaller, segments.  

From the following figures, it can be seen that, although again, the majority of kits showed no changes in the numbers of segments, almost 200 matches did show either a loss, or a gain:


Of the 81 who lost one segment, the Total cM shared decreased for 80 of them, but the Longest segment showed no change for 70 of those. And, for the 101 that gained one segment, 99 showed an increase in the Total cM shared, but 78 of those showed no change to the Longest segment.  

So those figures would seem to support the possible explanation for the 'horizontal' line of points, that the segments being lost, or gained, are smaller segments, rather than the longest. [and whether any of it is 'significant' would be a totally different issue, given that many of the changes are only in the range of 5-10cM.]  

I was intrigued by one match, who had lost one segment, and yet both their Longest segment and the Total cM shared had increased (by 23.5cM and 18.7cM respectively.) This was a case where a 'gap' between two small 6cM segments on chromosome 18, is now shown as matching, creating one segment of 31cM, another three segments remaining identical:

Another match I followed up was one where the number of matching segments increased by 3 yet the Total cM decreased by 1.8cM and the Longest segment decreased by 20.5cM:

 


In some ways, I don't know what to make of this - the total loss of a segment on one chromosome, but gaining four small segments on different chromosomes.  

The companies give us many such small matches so, according to their science etc, it must indicate at least a 'potential' relationship. But I certainly wouldn't be spending time looking for a genealogical connection to such a match!

The other match that gained three segments had increased both their Total cM shared, and their longest segment (by 28.0cM and 4.9cM respectively):


That seems a bit more 'reasonable' than the previous case, with an increase to the existing segment, and the 'discovery' of three other segments. 

But how relevant some of these segments are remains to be seen.

Closer matches

Finally, I looked for any changes to the matching with my closest relatives. 

In comparisons with my mother's kit, the MyHeritage WGS kit showed different totals on seven chromosomes, from those shown with the FTDNA upload. Two chromosomes showed decreases, the other five were increases, but all individual changes were less than 7cM, producing an increase in Total cM shared of 16.7cM. I'd need to research the particular start and end RSID points of the tests, to see if differences in those explain these changes (since I should match my mother along the full length of every chromosome.)

Comparing my kits to my uncle's, with whom I share 43 segments on each kit, six of the segments had changed slightly (one increased, five reduced), all changes less than 3cM. Three of the segments are all on chromosome one and at least the first segment is potentially due to wider coverage of the newer test, since the starting location has changed to exactly the same RSID point that my mother's kit did.  

The next closest eight matches, taking me down to a Total shared DNA level of 100cM, includes seven identified second and third cousins.  Of these, only one shows a change in the Total shared DNA, with an increase of 18.4cM on chromosome one.  In this case, the increase doesn't seem to be connected to a change in the starting location (which is actually quite interesting, since the starting location for this match on my FTDNA uploaded kit was already showing the earlier location - so why wasn't that kit showing as matching to my mother, and my uncle, from that point?) 

Since this 2c should be matching my uncle over the same range, I shall investigate this further.

But that can wait until another day!

1st and 2nd cousins - shared DNA variability

This post is a bit of "thinking aloud" - I have some data, but not a full answer for why the data shows what it does.

We know that the DNA passed on by the same two parents to their children will vary, such that, although every child will receive half their DNA from each parent, the level of shared DNA between the siblings will vary, depending on which 'bits' of the parents' DNA they each received. And that, as relationships become more distant, the quantity of DNA shared becomes even more variable for particular levels of relationship.  

This is why, for a specific quantity of shared DNA, several possible relationships are often predicted by the DNA testing companies.

When I first took a DNA test at Ancestry, my closest match was a predicted 3rd cousin, who shared 92cM with me.

Based on that quantity of DNA, Ancestry gives the following alternative relationships:




 And the "Shared cM Project" tool1 gives the following probabilities for the various possible relationships:




My match had tested more for ethnicity and 'general' information, and didn't know much about their family history so, based on the image the Shared cM project produces, and the level of shared DNA, I draw out a possible "family tree", showing where my match might fit into my family, along with what I knew about the family at the time:

 




[The only reason for not including the half relationships side of the diagram was to keep things fairly simple.]  

I then set to work on the genealogy - from which we discovered that the match actually seemed to be a second cousin, not a third, despite us sharing a relatively low level of DNA for that relationship. 

A question was asked, by one of the DNA experts, as to whether the match might be a half 2c - and that is a possibility I still bear in mind.

However, I have been interested to see the other quantities of DNA shared, as more of the family have tested over the years. 

I do have quite a few second cousin matches now, thanks to my grandmother being one of ten, but I'm concentrating here on just four of them - a single second cousin from my grandfather's side, and three second cousins from my grandmother's side, who are siblings to each other - and comparing them to myself and two of my first cousins.  This is because the closer relationships, of the siblings to each other, and of the first cousins to each other, are confirmed through the shared DNA, as well as the known family history.

So this is how we all relate to each other:


And these are the levels of shared DNA:


Below is a table of the averages, and ranges, of shared cM for particular relationships, taken from the DNAPainter diagram:


So, with the exception of the 39cM shared between match 5 and me, and of the 23cM shared between matches 1 and 6, all of the values do actually fall within the range for possible second cousins. 

However, the probability of the relationships being second cousins (or even half second cousins) seems to be classed as fairly low for many of the values:   


I have included the Ancestry predictions for the relationships in the following table:


As you can see, only two of the relationships (highlighted in yellow) are predicted to be possible second cousins.  If there is a "half relationship" situation, another two of the predictions (highlighted in pink) would be okay.

But Ancestry's predictions for all the other comparisons are for more distant relationships.

When I received that very first match, one of the first things I did was to put the shared DNA figure into a predictor and, if it hadn't been for the match then being able to give me a couple of names that I recognised, I would probably have been looking at the wrong generation of my tree, at least initially, to try to find our shared ancestry.

As I mentioned above, the question was asked as to whether my first match (and now that would mean their siblings, as well) might be half second cousins to me (and also now to my two first cousins). Since the respective grandparents were the second and fourth children out of ten in the family, with fairly regular "two year intervals" between them all, there would have to be a "story" behind that, if it was true.  

It's obviously not impossible, though, so I'm not discounting it and will continue to explore the possibility, through the clustering of other shared matches.

But, even if a half relationship between my grandparents and their siblings does become evident, it wouldn't explain the fact that the shared DNA, for the majority of the relationships, is still less than would be expected - and therefore, if I needed to search for how I connected to these matches, I might be looking in the wrong parts of my tree! 

So, one point I am trying to make is the importance of "doing the genealogy" and not just relying on such predictions.  Does the predicted relationship fit with the known family history, with ages, and with locations, etc?  If not, don't just assume the "most probable" prediction is the correct one.

Another possibility I have wondered about, is whether the predictions from companies such as Ancestry, and the Shared cM Project, might have a tendency to predict more distant relationships for those of us in the UK.  This could be due to much of the data coming from people with ancestry in the US.  It seems those in the US often have many more matches than those of us in the UK, and potentially, a higher level of "overlapping ancestors", which might create a higher level of shared DNA for particular relationships. And thus 'bias' the predictions.

I don't know enough about the wider field of DNA statistics to know whether that is possible, or whether other people in the UK have found similarly lower levels of shared DNA.  

But I shall certainly be checking the predictions for all my other identified DNA matches more closely in future, to see if those show the same tendency.

DNA match numbers

 Like many people, I imagine, I've spent some of January doing a bit of 'sorting and planning' to help me achieve what I'd like to during the year.  

So now I just need to actually do the things I've planned!

One of the first tasks was to update the graph of how many close matches I have at Ancestry.  At the time of my last post, the review of 2025, the number had increased to 376 close matches.  I now have 378 close matches - and I also noticed yesterday that I had exactly 20,000 matches, in total, there. 

(But that total had already increased to 20,003 by this morning.)


Since I was interested in the rate of increase, I also looked at the change in the totals over the years:


The Ancestry test was launched in the US in 2012 and then in the UK, in January 2015.1 One can see that, after an initial slow start, for me, the three years between 2017-2019 saw the most new close matches, with an average of 50 across those three years.  Numbers have since reduced, averaging 30-35 per year, but are quite variable.

 From the graph, many of the years seem to show a higher rate of increase in the early months of the year - probably due to the sales in December, and 'Christmas gifting', which results in more kits being processed during those early months.

It will be interesting to see if the early part of this year shows the same sort of curve. Although kit prices at Ancestry were reduced, those of one of the other companies, MyHeritage, were even cheaper.  

And, with the news that MyHeritage was moving on to "Whole Genome Sequencing" (WGS)2, perhaps more people will have opted to purchase kits from there instead?

Either way, I'm sure, with this change, there will be a surge in the numbers at MyHeritage - if only because of all those who have already taken DNA tests elsewhere now deciding to try the new test, as well. 

I admit it - I did too.

My kit is currently in the "WGS in progress" stage, and I am looking forward to receiving the results.  It will be interesting to see how they compare to those received from the other companies I have tested with, and especially with those kits I transferred to MyHeritage.

Unfortunately, I've not been tracking numbers there in the same way, with those transferred kits - but perhaps it will be worth starting to do so, once these new results are in.

I'm finally ‘English’! (MyHeritage ethnicity updates)

 It seems that, for many people, when considering DNA testing, it is the 'ethnicity' that they are mainly interested in - how "English" they are, or whether they are a "Viking", or a 'native' to whichever country they live in.  I remember when I first received my Ancestry results, and contacted my closest match - they hadn't even realised that they would be able to find other people who were genetically related to them.  

Whereas, for me, it has always been the DNA matching that was important, in order to confirm (or disprove!) my family history research.  I think that's one advantage of being in a family history organisation like the Guild of One-Name Studies - there have usually been 'pioneers' in any aspect of the research, people who have already gone on ahead and have fed back some of the pros and cons they've discovered.

And so I was aware that, for the ethnicity estimates, the clue is in the name - these are 'estimates', and they depend very much on which reference populations the companies are using.  That didn't mean I took no notice of them - I just took them 'with a pinch of salt', especially when one company, MyHeritage, indicated that I had no English DNA.  

Several of the companies included the UK as part of a general "Northern Europe" grouping, so I hadn't actually noticed at first glance - the following is from a screenshot I took in 2017:


I think one often doesn't notice when something is 'missing', only when it's there but doesn't 'fit'.  So it was only when I explored the maps and figures in more detail that I realised the estimate was showing me as having no English:



2017 ethnicity estimate from MyHeritage

  

This was rather strange, considering that, with the exception of one 5xgreat grandfather (a German, who was in England by 1802), every one of my identified ancestral lines is either in England, or in the South Wales border area!

Since these results seemed so far 'off', I haven't paid much attention to the ethnicity estimates at MyHeritage over the years.  

But the companies are always refining these reference populations and MyHeritage has recently released a new update, version 2.5. You can see their blog post about it at https://blog.myheritage.com/2025/02/introducing-ethnicity-estimate-v2-5-improved-dna-ethnicity-model/

I hadn't actually noticed that my initial results, which were from when the ethnicity estimates were still described as "Beta", had been refined slightly, at some stage, by version 0.95:


That had brought in some English, at 3%, with hints of several genetic groups from specific areas within England.

But now, with this latest update, the estimate has changed considerably and is much more in accordance with my known ancestry:


Even the "Germanic" is now showing up!

The above results all come from the same DNA test that I originally transferred to MyHeritage, so it is not that my DNA has changed in any way.  What has changed is the method by which MyHeritage are analysing it, along with their updated reference populations.

As Roberta Estes states in her blog about the update, "the whole purpose of updating ethnicity results is to obtain either more granular results, or more accurate results, or both." 1

In my case, the update definitely seems to have produced both!

DNA progress - Ancestry Pro Tools and my NAYLOR/NAYLER family

 I have made a start on reading about some of the other bloggers' experiences with Pro Tools and found that the main feature they appreciate is the one that I think will also be the most useful to me - the ability to see how much DNA is shared between a specific match and those other matches that the specific match and I have in common. 

I was intending to illustrate this with some data from a few of my first and second cousins.  However, that post will have to wait a while, since a couple of recent new matches on Ancestry have sent me off on a sidetrack.  Since they are also good examples of how Pro Tools can help, I'm going to use the data from them instead.

So how does Pro Tools help?
The two matches happen to be a mother and son. How do I know that?  Because Pro Tools tells me so:


 
The mother matches me by 47cM across two segments (unweighted shared DNA 52cM, longest segment 45cM).  She has a family tree - but there's only one person on it.  The son matches me by 26 cM across one segment (unweighted shared DNA and longest segment both 31cM). He has an unlinked tree, with about fifty people on it.  

Previously, both of the matches would have appeared on my "4th cousin or closer" match list, since they both share more than 20cM with me.  But, when looking at the shared matches, although they would each appear when I viewed the other's list, I would not have been able to confirm the relationship between them, because I only had the family trees to work with. 

Whereas now, with the Pro Tools, Ancestry shows me the quantity of DNA they share between them, as well as telling me the predicted relationship.

A parent/child predicted relationship is the only one that (as far as I am aware) will always be correct and, as relationships become more distant, the predictions by the DNA companies become less reliable, since they are based on a range of possibilities for the quantity of DNA shared. 

But this information is still a major benefit whenever relatively close members of a family have all tested their DNA.

For example, in this case, having seen that the son is the home person on his family tree, I can immediately identify which side of the tree is the relevant one to research, in order to look for our shared ancestry, because I know the connection is through his mother.

If a match happens to have first or second cousins tested, and it is possible to identify where their common ancestry with the match is, then each of those generations back to their shared ancestor also narrows down the relevant portion of their family tree that I would need to focus on.

Without Pro Tools, I might not be able to identify such cousins - in fact, they might not even show up on the shared match list, if the DNA they share with me has fallen below 20cM.  But the fact that Pro Tools seems to show the shared matches where just one of us shares at least 20cM with them, means there are matches on the lists, which I would not have previously seen.

To illustrate this - based on the old 20cM threshold, only twenty-four of my matches would have shown up as shared matches to the mother.    Eleven of these share between 21cM - 25cM with me, five are in the 30cM - 46cM range, and five between 54cM - 59cM. Then the closest three share 78cM, 146cM and 250cM respectively with me.

The last two are my half first cousin, and a half 1st cousin 1 removed, so I recognise them and know where they fit in my family. The next largest, at 78cM, has a family tree with thirty-six people on it, including a Frederick NAYLOR in Hawaii (supposedly b 1870, no birthplace, and no death details given.)  Now, NAYLOR is one of my ancestral names, and it is relevant to the two higher matches, as well.  The unattached family tree on the son's profile also shows a descent from the same Frederick NAYLOR, in Hawaii, as the 78cM match's tree does.

But, other than identifying that these matches are 'potentially' connected to my NAYLOR line, and that the two new matches will probably connect more closely to the 78cM match, based on their tree, I don't think that I'd have been able to identify much more about them.

However, with Pro Tools, there are fifty-three shared matches shown between the mother and I, rather than just the twenty-four.  As well as her son, these include a predicted half-brother or nephew, and seventeen matches with a predicted relationship involving the term "1st cousin".  Nine of these, including the half-brother/nephew, would not have even shown up as shared matches to me, without the Pro Tools, since they share less than 20cM with me.

But they are all close enough to the new match that I should be able to work out how most of them connect to each other.  

A downside to pro tools?
Yes, there is a downside to all this additional information (at least, for me, and the way I work.)  

Previously, before taking out the Pro Tools, I would check on my new matches at Ancestry most days, in order to keep track of the number in the "4th cousin or closer" category.  If that total had increased, I'd view those matches first, check for any shared matches between us and, if there were any, and I'd already made some progress in identifying our connection, I'd add a note to that effect to the new match's profile.  Once any close matches were dealt with, I'd check through the other, more distant, new matches, looking for any that did show shared matches with me and, again, add a note to their profile. Since, without Pro Tools, the only shared matches had to be ones sharing over 20cM with me, I frequently found these, more distant, new matches did not show any shared matches with me.

But, of course, now that Pro Tools means I can see any shared matches that share greater than 20cM with the new match, even if they only share down to 9cM with me, just about everybody shows some shared matches (in a couple of cases seen so far, there's been nine pages of them!)

So, this makes the task of viewing new matches so much more time consuming, and I am going to need to modify my routine - perhaps not even checking the shared matches unless I have some clear indication that there's a 'potentially findable' link to them.

Returning to the two recent new matches…
As indicated above, based on both family trees and other shared matches, it seems the family share ancestry with me, at some level, through the NAYLOR family.  The NAYLOR line is one that quite a few of my matches seem to connect to. (I mentioned the NAYLOR cluster, "Group 1", in my post on 9 August 2017 at https://notjusttheparrys.blogspot.com/2017/08/ancestry-shared-matches-and-new.html.)

Some years ago, because of the number of matches in this group, I constructed a 'rough' family tree, on paper, predominantly derived from other people's family trees (with a little bit of 'fact checking'. :-) ) 

It has remained on paper ever since - mainly because, once I discovered a Herald at the College of Arms in the early 19c was a possible sibling to my line, sifting through the information to distinguish fact from fiction became much more difficult, since there is so much of it!

But now, with Pro Tools showing how my matches relate to each other, I think I will stand more chance of being able to fit my matches into the NAYLOR line, and actually confirm the links, than I was able to do before (bearing in mind that many of them either have no tree, a partial tree, or even an incorrect tree.)

So that has been my 'sidetrack.'  This week I have been entering all of the rough information into FamilyTreeMaker, the program I use for my own personal family history. I am now beginning to check the 'facts' more thoroughly, as best I can, before making the information publicly available on my Ancestry tree.

I don't know whether I shall be able to resolve who the parents of the Fred NAYLOR in Hawaii were - although the son's tree has his birth as England, I do know that other records indicate it was in Australia (and I think there's one record that suggests the USA instead).  There is a potential Fred born in Australia - and at least one researcher on Ancestry has placed the Hawaii Fred into that family - but there is an issue in that Fred's marriage in the US indicates his father was also called Frederick, whereas the father in the Australian birth was a Charles.

It is a common frustration, when an emigration causes such a break in a family line.  I am hoping that, by placing many of my DNA matches onto the tree, I will be able to develop, and test, theories as to where Fred fits.

But it is still a 'work in progress' - and there will be some caveats to the predicted relationships (which I hope to explain further, when I finally get that "1st and 2nd cousins" post written.)

In closing, I'll include the details of two monuments to the family, reported to be in the church of St John the Baptist, Gloucester.1:

DNA progress - first steps

 At the end of 2023, Ancestry released their "pro-tools" in the UK.  This is an additional set of tools for family history, and for more advanced DNA research, than are available through their normal subscriptions. But it does require both a current subscription, and additional payments.  Although I was 'tempted' when it was first released, I left it for a while because that was a busy period and I knew I wouldn't have time for research. But I was then disappointed to discover, when I returned to it later, that the monthly cost had already increased from £4.99 to £7.99.  

That put paid to that!

However, a recent post on FB alerted me to the fact there was an offer on (until 20th January), and I have now been able to take out a cheaper option for six months.  I'll see how I get on with it, and how useful it proves to be, as to whether I continue to subscribe, or not.

Of course, the additional tools and information should be of help - for example, it is now possible for me to see how much DNA is shared, and the suggested relationship, between one of my matches and the matches we share.  The thresholds at which the shared matches are shown is also less restricted than it is with the standard tools.  

This will be very useful in cases where several members of a family have tested but perhaps only one or two of them share 20cM or more with me, so the more distant ones didn't previously feature in the shared match list.  This should  make it easier for grouping matches and allocating some of the more distant ones to potential ancestral lines. 

My main hesitation is how to get to grips with recording all of the additional detail.  So my next step will be to read up on some of the blog posts by other researchers, to find out how they are managing the data.

DNA Update

In my last post, I mentioned the need to focus on my own family history again.  One aspect of that is making the most of the opportunities that DNA provides in tracing more distant or 'lost' relatives.  It's been a while since I did any serious work with my DNA results so, as a start, I've updated the graph I initially posted in April 20201, showing the numbers of my matches who are predicted to be my "4th cousin or closer" at Ancestry:


I'm currently up to 345 matches in that category.  As can be seen, the rate of increase has slowed down since early 2020, but new matches are still coming in relatively frequently.  I check Ancestry most days and, whenever there are any new matches, the first thing I do is look to see if they have any 'shared matches' with me, since those can help with placing the new match in the correct area of my family tree.  Although the more distant new matches often show no shared matches, most of those in the "4th cousin or closer" category will match 'somebody' and so I can add a note about this to the profile I see for them.   

That's about as far as I've been going over the last few years.  

Back in 2017, I'd worked out how matches tended to group together and what that indicated.2  But everything DNA related seems to have become much more 'complicated' over recent years, what with increasing numbers of matches, changes to the company websites and the information that's now available, and also, consequently, changes to some of the tools used for managing the data.  

It might take me a while to catch up with the best methods for dealing with all these matches now, but at least the "basic principles" about DNA transmission haven't changed, so that the task doesn't feel impossible.

Updates will follow as I make progress!

Ancestry DNA matches - passing 200 "4th cousins or closer"

I was planning to post an update to my Ancestry DNA match numbers when I reached 200 4th cousins or closer.

But clearly someone, somewhere, has a sense of humour!

Having been slowly creeping up towards 200 over the last few weeks....



....yesterday when I checked, the total had jumped from the previous day's 198, up by three to 201, thus missing out 200! 😀

An increase like this is what one might expect, when a group of family members all decide to test at the same time.  The closest match is a predicted third cousin to me and then the other two are both predicted 4th cousins.

I think it's the first time I've received such a batch of close matches, all on the same day.

Initially. all three matches showed with unlinked trees - but at least they were trees that featured, not just one of my surnames, ALLEN, but also the similar use of a particular middle name.   The trees have since been linked to the matches, so I can now identify the relationships between the three of them.

Another good thing was that, out of the nine other DNA matches shared between myself and the closest new match, I have already identified a common ALLEN ancestor with seven of them, and another one connects to the ALLEN surname, although we've not proved who the shared ancestor is yet.  The ninth match has two other shared matches, creating an isolated group that I hadn’t been able to link into an ancestral line, so perhaps these new matches might lead to the opportunity to do so.

One would think that, with all this information, the connection to the new matches should be obvious, but I didn't recognise the oldest ALLEN ancestor in their line. 

However, following some research today, I have now written to the match.  Potentially, if there is any doubt about the connection between their oldest two generations, then I might just have the answer. 🙂

Ancestry close matches

I was beginning to think that my comment on the 12th January - that everyone was just waiting for Christmas to buy DNA tests - was clearly not justified, since there was then a lack of any new close matches for almost another fortnight, during which time 23andMe announced they were laying off staff.  When Ancestry also then reported lay offs, on the 5th February, it just emphasised how much of a downturn there has been in the DNA testing market.

However, it hasn't been all "doom and gloom" since - I've received seven new "4c and closer" matches since my comment ( 24/1, 1/2, 11/2, 13/2, 19/2, 21/2, and 23/2) bringing me up to a total of 190. 

Out of these new matches, one was someone who has also tested at 23andMe - which is useful, since I have identified the potential shared ancestor with this match, and that helps to confirm some of the shared lines at Ancestry, which were suggested through match clustering.

Another match was a predicted 3rd cousin - by the time I'd explained how our shared matches enabled me to identify approximately where in my pedigree they fitted, ie a shared match who is a first cousin of mine meant my paternal side, sharing with certain second cousins of mine narrowed it down to my paternal grandmother's ancestral lines, and a shared third cousin meant the connection was most probably through my great grandmother HAYNES' ancestry somewhere, they'd discovered just how closely they were related to that third cousin, and it was clear exactly where they fitted into the family! 

The other matches haven't been quite so easy to place, varying from no pedigree information and no shared matches, to both good pedigrees and at least one shared match, with a possible suggestion of which of my ancestral lines they will connect to, based on the shared clustering.  

So, still a bit of research to be done for most of the new matches, but with a possibility of success for at least some of those.  

Which makes for steady progress towards my goal of identifying all of my '4c and closer', as well as giving me some more examples to use in a presentation that I am currently working on, on how helpful shared match clustering can be.

Another potentially identified DNA connection

Isn't it nice when things just work out?

I haven't done much regarding DNA over the past month or so, due to other activities.  But I have tried to keep up with the "new" events, such as the MyHeritage changes.  I'll write more about my results at that site at another time - this post is about an Ancestry find.

Late last night, (probably too late, I should have been on my way to bed, but you know that thought, "I'll just check one more thing" 🙂) I decided to look at how many '4th cousin and closer' matches I have on Ancestry.  I thought it would probably be 81, which is what it went up to a week ago. But the numbers have been increasing more rapidly recently, with five new matches in that category since the beginning of the year, so I am ever hopeful of an increase.

The total was 82!

I quickly searched for the new match -  no tree and only a 'good' confidence level, with 22.7 centimorgans shared across 3 DNA segments.  That could mean three segments at about 7.5cM each, or it could be one longer segment and a couple of smaller ones.  I won't know unless they transfer their data to another site.  Still, it would be worth following up when I get time.

But then I looked for any shared matches.  Often there are none, as shared matches only show for matches in the "4th cousin and closer" category so, if this match also matches some of my more distant matches, the more distant ones won't show up on this person's profile.  But, this time, there was one shared match shown, predicted 'high confidence', with 38cM shared across 2 DNA segments.  And with a tree of eleven people.

I keep a running total of the numbers of matches I have, as well as noting the names of new matches and anything interesting about them (like whether they have a family tree, or a surname in common with me). So I could tell that the shared match had appeared on the 9th of January and, at that time, was not showing a family tree.  So I am fortunate in that it looks like they are interested in finding out more about their ancestry, as they have taken the trouble to add some family details.

There were two surnames in common with me, LEWIS in Wales and ALLEN in London.  The Welsh one was not in one of "my" counties, so I took a closer look at the ALLEN first.

There were no dates, just the location for the one female ALLEN's birth in London.  But her marriage was shown, so that gave me her husband's name.  Armed with that information, I was able to identify their marriage, in 1926, on Ancestry.  London records are well represented on the site so I didn't just find the civil registration index but also an image of the actual parish register.  That gave me the bride's father's details, Herbert Henry ALLEN, a poulterer.  As the bride's age was shown on the certificate, it didn't take long to find the family in the 1911 census, Herbert Henry (33), with wife, Ada (32), and children, Edward (12), Florence (11), Herbert Henry (10), Frederick (7), Joseph (6), Dorothy Violet (5), Cyril James (4), Bessie Maud (3) and Frank Reuben (1).  From there I checked the 1901 census, which showed Herbert and Ada, along with the two older children.  Herbert's birthplace was Lambeth in both censuses.  Ada's and the children's varied from Lambeth to Brixton and Stockwell, but these are fairly closely connected areas in south west London, and all familiar from my own family.

The next step was to identify the marriage of Herbert Henry ALLEN to Ada - I used FreeBMD for that and found that the most probable entry was in September 1898, in Camberwell.  Back to Ancestry to search for the church records.  Yes, again the entry was there - Herbert Henry ALLEN, aged 20, married Ada SPRINKS on September 12, 1898.  Herbert's father was a John ALLEN, Perambulator Maker.

Now that's exciting - because my John Prosser ALLEN, snr, was also a perambulator maker. And, on February 10th, 1878, my John, with his wife, Sarah, christened their son, Herbert Henry ALLEN!

Obviously, I need to continue to work through the details, and check for my John and Sarah in records such as the censuses, to make sure their Herbert is with them, or not, as appropriate, and that there's no evidence to suggest this isn't the right connection to my DNA match.  I also need to contact the shared match who appeared on my list yesterday, to confirm whether or not they connect to the same family line.  And, of course, it would be great if both matches transferred their raw data to one of the other DNA sites, so that we can check exactly where we match on the DNA.  That would also mean I could look for more evidence, for or against the connection, amongst my other DNA matches.

ALLEN is a fairly common surname, so I don't follow up general references to it on my DNA matches' surname lists - but, who knows, if these two matches do transfer their data, perhaps there'll be others matching over the same segments and with the same surname.  I'd certainly be following those up then!

Just going back to the quantity of DNA shared - 38cM is the average for 4th cousins (based on Blaine Bettinger's Shared cM Project*) whereas we actually appear to be 3rd cousins.  So the shared DNA is a bit on the low side, but well within the range.  The match with 22.7cM could be more distant, but I am hopeful that they will still be within the range of my genealogy!

(And I did eventually get to bed last night - although it was 'today' rather than yesterday!)

My Ancestors and their Descendants - my potential DNA Tree

Earlier this year, our ISP informed us that it would no longer support personal web spaces - a poor decision in my view (of course!)

The upside of this is that it will force me to do the web site "re-write" that I set as a goal in 2015.

The downside is that I haven't done it yet, so my Parry Surname Research (Family History and the One-Name Study) site has disappeared.

Theoretically, since the site was written in html and css, it would have been quite easy to just upload all the files elsewhere.  But then there'd be little incentive to get the rewrite done.  And, with the development of the Guild's "Members' Websites Project", it seems an ideal opportunity to separate out any personal family history from the Parry One-Name Study information, and to ensure the long term survival of the ONS data by placing it on the Guild's site.

So that's the plan. And it is in progress (slowly).

But today, frustrated at the loss of my "DNA tree", which I really need to accompany the autosomal DNA project I have set up at Family Tree DNA, I decided to try uploading that here, on Blogger.  It's taken a bit of tweaking of the coding, especially on the page width, which I hope I don't accidentally delete, but at least the information is available again:

My Ancestors and their Descendants - my potential DNA Tree

And now I've been reminded of just how many of my ancestors and their descendants I still need to trace. ☺

Other activities - the Genealogy Do-Over interlude

Sometimes I keep a diary.  And sometimes I don't.  And, when I don't, I often look back and wonder what I did for all those days! 

So, for my own future reference (and for any descendants who ever wonder what their "x times great" grandmother did), here are a few notes.  Firstly, I resurrected another hobby - sewing.  Prompted by the thought that the Saturday night banquet at the Guild of One Name Studies Conference has seen me wearing the same dress for a number of years, I decided to make a skirt - which then developed into making a skirt, top, evening bag and several other items just for the fun of it.  Getting the critical items finished on time did involve stitching at 5.30 am on the morning of the banquet but, since I'd woken up early anyway, it seemed like a good use of my time.

Finishing the sewing so early at least left me free to chat to people in any spare time during that day.  And chat I did, as the Conference is a great time for catching up with "old" friends, as well as making new ones.  Some of the conference sessions were recorded and the videos are available on the Guild's YouTube channel - I am looking forward to watching some of those sessions I missed, due to there being two sessions running at the same time.  It would be hard to pick highlights from the Conference, as it was all so good, but I think Jim Benedict's interactive session on "Succession-Proofing your ONS" probably stands out as providing the most laughs, as the various groups debated why *their* method of succession-proofing was best (Debbie, have you bought that spaceship yet?).

We heard more about the Guild Members Websites project over the weekend and I took the opportunity to chat with Mike Spathaky about his Cree Study site, and the various different options for producing websites.  It was Mike who had asked me, on the Guild hangout in February, why I was thinking of moving my PARRY ONS site to WordPress.  As a result of our discussions about the benefits, and potential longevity, of html, I now have a few more reasons for not doing so.

For the first time at the Conference, on the Friday afternoon there was an informal meeting for those interested in DNA testing.  Despite me being totally disorganised, having arrived at the hotel later than planned, and then walking all the way to my hotel room, only to discover that my key didn't work, so that I was still carrying around half my belongings at the time the meeting began, things seemed to run smoothly as we all shared about our various levels of involvement with DNA testing.  No doubt we will all be building on this in the coming months and years. 

I have frequently come away from the Conference with some snippet of Parry information, whether it has been from Marriage Challenge certificates passed on to me, or references I have found in books on the bookstall, or in someone's talk, etc.  This year was no exception, as Jo Fitz-Henry very kindly supplied me with photographs of some Parry gravestones that she had come across.  I'll write more about those on the Parry ONS blog.

The Conference was held at Brigg in Lincolnshire and my route there provided an opportunity to drive past RAF Scampton, one of the bases where my mother had been stationed in her WRAF days.  When planning my conference attendance, I had originally thought of contacting the museum on the base with a view to arranging to visit enroute to Brigg.  It was probably a good job I didn't do that, given how time went.  But that's now on my "To Do" list, for another occasion.

Moving on from the Conference in March, the next main event was the WDYTYA? Live Show in April which, for the first time, was being held at the NEC, Birmingham.  This provided another incentive to do some sewing!  Several years ago, Dick Eastman blogged about the Progeny Charting Companion program and its ability to produce an embroidery pattern from your family tree.  "What a wonderful idea," I thought, and soon after that, I was able to replace my 35 year old sewing machine with a new one capable of following such a pattern.  Then came the "busy-ness" of the last few years.  I still haven't tried that program but, ever since I discovered some ancestors who were "artisans in fireworks", I have had an idea in my mind - and I finally managed to execute that in time to wear to the show.


Okay, the hall was too warm to actually wear the hoody *in* the show, but I'd achieved my goal!  I'm now on the look-out for other items I can embroider with bits of my family history!

At the show, I was helping to man the ISOGG stand (ISOGG = International Society of Genetic Genealogy).  We were so busy throughout most of the time that I was amazed I hadn't lost my voice - it seemed like every time I sat down, another visitor would arrive with a query.  Hopefully, we will be seeing a rapid increase in DNA testing in the UK over the coming months, especially now all three of the main companies (FamilyTreeDNA, 23andMe and Ancestry) are marketing their products here.  Another enjoyable aspect of WDYTYA was meeting many of the ISOGG members who came across from the United States to assist with the practical aspects of testing on the FTDNA stand.  Although ISOGG itself is an independent organisation and, as far as possible, information is always presented without bias, many of us would admit to having a personal preference towards FTDNA, not least because they are the only testing company that support the YDNA and mtDNA projects.  (Having taken the autosomal test at all three companies, I think it only fair to mention that I can find pros and cons for each of them.)



There was a fair amount of catching up to do, after the three days of "doing nothing" at WDYTYA, which was followed by a deadline for some paperwork.  But, now that's been met, I find myself actually restarting my Genealogy Do-Over. 


I wonder whether I can get to week 13 without any further interruptions!

My First AncestryDNA Tree Hint

Last week I noticed one of those leaves.  You know the sort - the little 'hints' that appear on  Ancestry, to indicate that they have identified an item in their records, or in someone else's pedigree, which the company's search tools suggest could possibly relate to someone in my own pedigree.  When I first put my tree online, there were over 1000 of these and some of the suggestions seemed so ridiculous to me that I soon decided to ignore the little leaves.

But not this one.

This one was on my DNA account.  That's the same pedigree for me, but being matched to a specific group of people as comparisons, people already identified by Ancestry as connected to me through shared DNA. 




Excitedly, I checked my match's details.  A private tree.  Never mind, send a message - and wait.  (Did they receive the message?  How long should I wait before sending another, 'just in case' the first went astray?  Oh, aren't we genealogists so impatient at times!)

I receive a reply. Hurrah!

And, yes, we do appear to have a common ancestor.  Or, more correctly, a common ancestral couple.  Thomas DOWDING (b. 1768 d. 1857) and Ann WHATLEY  (d. 1861), living in Donhead St Andrew.  I descend from their son, George , who married Mary COLLINS and my match descends from their daughter Jane, who married a John HOWELL.  I show the family on my "DNA Tree" at http://homepage.ntlworld.com/im.griffiths/parryfamilyhistory/personaldnatree.htm (search the page for "Whatley" to find them, as I haven't yet added links to specific families).

The research for this family was mainly carried out by my mother, and it is part of my "Genealogy Do-Over" goals to check her work during this year.  But, at the death of Ann DOWDING, the widow of Thomas DOWDING, the informant was a John HOWELL, and I have found some look-ups I did for Mum on Ancestry, back in 2005, relating to the John HOWELL, so we were definitely considering that family as another descendant branch.

John HOWELL appears to have first been married to a Mary (HO107/1175/5/ED8/F22/P6) and had at least four children by 1841.  There is a possible death for Mary in March 1849 and, based on the 1851 census, John and Mary had, had further children by then (HO107/1849/62/24).  John then marries Jane DOWDING* and has at least three children, Emma J, Georgina and Abigail.

My DNA match is descended from Emma Jane HOWELL.

The Ancestry relationship prediction is that we are 5th-8th cousins.  From the genealogical relationships, we are 4th cousins , once removed.

Unfortunately, at Ancestry there is no chromosome browser, so we cannot see where we share DNA.  If we could, it would enable us to each identify our other matches over the same area.  If those matches then matched both of us there, this would mean we all shared the same common ancestry somewhere on the lines through Thomas or Ann (either their descendants, or, as descendants of one of their ancestors).  Thus it would potentially help us find our connection to these other people, who might not have sufficient detail in their pedigrees for us to spot the link from the pedigrees alone.

Also, currently, even though the two of us have found common ancestors, it does not necessarily follow that the shared DNA definitely comes through them - so, finding other matches who share the same DNA segments with both of us would enable us to see whether their pedigrees have the potential to link to this same ancestral couple, which would help to confirm where the DNA actually came from.

I wonder if my match might be willing to upload their data to Gedmatch, so that we can actually compare DNA - currently, transferring the data elsewhere is the only way to make up for the deficiency in the Ancestry provision.

So, there is still a lot to confirm, but at least this 'shaking leaf' does seem to be a hint in the right direction. 


[*Jane appears to have been married before as well - a Jane DOWDING marrying an Elias DUNFORD in 1842, with Elias dying in 1843, and a 'Jane DUNFORD' then marrying John HOWELL in 1849.  These details do still need confirming.]
