A New Hartley BigY test results are in:
John R is the 7th BigY Hartley tester in the group of Hartleys that I am related to. There are other Hartley branches in the world, but they are not at all closely related by YDNA. I did an initial analysis of John Roberts STR results last week here.
The A16717 Branch of Hartleys
So far all the Hartleys that are related to me by YDNA are under the branch A11134. John R is further under the A16717 branch. This is an important branch of Hartleys as the genealogy is well known:
Ross has not taken the BigY test, but John R, Lawrence and Michael have. Michael has taken the older BigY 500 test. Before Lawrence tested for BigY, Michael was designated as A11134. Lawrence further designated the branch as A16717. John Robert and Lawrence could potentially form a new branch separate from Michael.
Comparing BigY Matches
I have compared John R, Lawrence and Michael to my results:
Here are the first two on my list of Non-Matching Variants. This list can be confusing because it could be a non-match because I have the variant and John R does not, for example. Or, it could be that John R has the Variant and I do not. I put those variants that do not match my results into a table:
Here I have color coded the non-matching variants.
The Yellow Variants
These are the variants that are in my brother’s and my Branch (FT225247) . These are the SNPs in my Branch:
There are 7 SNPs in this group. The yellow SNPs above account for 6 of the 7 SNPs. But where is FT135932? When I check John R’s results I see that he is not positive for this SNP:
I’m guessing that my brother had this SNP and I didn’t or didn’t have really good results for this tested SNP. Here is my brother Jim’s comparison with John Robert:
This implies that my brother James tested positive for FT135932.
Blue and Orange Variants
We know about the blue variants. This is the SNP label used to define the Quaker Hartley Line. The orange SNP is BY26739. This SNP is more difficult to explain. For one reason, a comparison between my brother and me show that is also a non-matching Variant.
If I have BY26739 and Jim and John R do not, that would explain things. Here are my results for that SNP:
It looks like the reads were not great, but the best reads they did have showed that I was positive for BY26739 two out of three times. I see from a previous blog that this was Jim’s results:
This was considered to be not derived, probably because there were 6 good reads which were all negative for this SNP. Here are John R’s results:
These results are even worse than my brother Jim’s. I see that the 4 best reads show no mutation at that location for John R.
The Green Non-Matching Variants
These are SNPs that my brother and/or I have. Here is an expanded view:
I don’t have a good explanation why these SNPs are not in my Block tree. One guess is that they may be from regions which are considered unreliable.
The Private Variants for the Quaker Hartleys should be the numbered variants shown in the chart above. These variants formed in the Thomas Line in the generations following Thomas Hartley born 1700. John R has three, Lawrence has 6 and Michael has two. That should mean an average of about 4 under the Quaker Hartley group of A16717. I’m not sure why the current Block Tree shows an average of three Private Variants. I notice that the old Block Tree before John R tested had an average of two Private Variants:
If these private variants matched between John R and Lawrence, then there would be a new Quaker Hartley Branch of SNPs. However, for that to have happened, Thomas Hartley born 1700 would have had to have had a new mutation that his brother Roger did not have:
Summary and Conclusions
- The recent BigY testing for John Robert put him solidly in the Hartley Quaker Line and confirms common ancestry as shown in the chart above.
- Differentiation between the two lines: Thomas Hartley and Roger Hartley were difficult as Thomas would have had to have had a SNP mutation to show up between John Robert and Lawerence.
- Differentiation was made in my previous Blog based on STRs which was useful.
- The BigY may undergo a manual review, but I don’t see any obvious changes that would be made.
- The Quaker Hartleys now have the largest group of BigY tested Hartleys in the A11134 Hartley group.
