The long awaited Nutter BigY test results came in. As expected by previous testing, he is A1134. The tester’s name is not Nutter but changed along the way at some point. I will call the tester Nutter or Michael for privacy reasons. Here is my list of BigY Matches:
After my brother, the new tester, Michael, is my next match. This may or may not be significant. the listing is based on the number of Non-Matching Variants. I have fewer Non-Matching Variants with Michael (other than with my brother) than with other BigY testers. I will be looking at Variants in greater detail later in this Blog.
I and my brother are fifth and sixth on Michael’s match list. The first 7 testers on the list are Hartleys (other than Michael). After that, there are other surnames. This indicates to me that Michael’s ancestors were likely Hartleys at some point in history. Tester #8 on the list Mawdsley and those after likely have a common ancestor before the time of surnames. Also Mawdsley and others have an earlier Haplogroup than the first 7 testers.
Michael in the Block Tree
One way that FTDNA shows test results is in a Block Tree. Here is the Block Tree from Michael’s viewpoint:
The part that says ‘Your Branch’ actually has three people in it: Nutter plus two of his Hartley matches.
I didn’t show that part of the Block Tree that has Mawdsley. He is further to the right under A11132. This shows that:
- Michael is the only Nutter under A11134
- My branch of FT225247 on the left has 7 variants under A11134
- There are 4 variants under A16717
- Under Michael’s branch there are 3 Private Variants on average
- The people in the bottom block represent now. That means the time back to the A11134 should be about the same for each of the three branches above.
Michael’s Private Variants
Why are these important? These represent Michael’s Line since the common ancestor of the A11134 group that he is in. Above, note that those in Michael’s group have an average of 3 Private Variants. However, right now, Michael’s results show that he has two Private Variants.
These two Private Variants show as numbers which are position numbers on the YDNA. So far, no one in the world has tested positive for these two positions. Once a match is found to one of these two Positions, they will form a new branch of mankind. This would be a branch that is likely in common with the Nutter name.
Position 15646418
This position is already in YBrowse. That is probably from when Michael tested with another company.
That SNP is named Y354187. The Y designation is from YFull.
YFull gave this SNP a name when Michael uploaded his results there last year.
5672076
I suspect the same is true for 5672076. This SNP is called Y354148:
Comparing Michaels Results with Other A11134 Testers
This part may get a bit boring, but it is necessary. There is only one way to match with another tester. However, there are different ways to not match:
- One tests postive and one test negative for a SNP
- One test positive and another’s test does not cover that SNP
- One tests negative and another’s test does not cover that SNP
Then there are incomplete test results which further complicate matter. Usually there need to be about 10 reads to have a good test result. If there are less than 10 reads or some reads are positive and some are negative, you get into a grey area.
Here is what I have so far in comparing Private Variants:
This shows who tested for what:
- Y means positive
- N means negative
- NT means the test did not cover that position
- ? means inconclusive
Above, Joel and Jim are A11134 > FT225247; Steve, John N. and Nutter are A11134 and Michael, Lawrence and John R. are A11134 > A16717. I am not sure what the blanks mean.
Here I’ve added a column for Nutter’s FTDNA results as the previous column was for his other test. I was already tracking SNPs Y354148 and Y354187 which I mentioned above. I would also like to add the SNPs in my branch as there are so many.
Here I have shown that Nutter has none of the 7 SNPs in the branch of Hartleys that my brother and I share. Next I went through the Private Variants of the other BigY Testers and checked to see if Michael tested positive for any of those Private Variants:
This shows that Nutter did not test positive for any of the other testers’ Private Variants. For example here is Nutter’s results for 11071280 which was one of Steve’s Private Variants:
Because Nutter’s Genotype is the same as the Reference, that means that Nutter is ancestral or not positive for that Variant. It is confusing, because these results were found in a download called Derived Variants (which is the opposite of Ancestral Variants).
What this means is that no new branches should be formed based on Private Variants. If my analysis was correct above, it also indicates that none of the other 7 Hartley tests covered the Nutter Private Variants. Nutter should have on average 4 Private Variants, so the two that he has are probably right. That means that the Nutter line had mutations about twice as slowly as the average. On the other hand, my Harltey Branch had 7 mutations during the same time period with mutations about as twice as fast as average.
A11134 Time Tree
Nutter is not yet on the FTDNA Time Tree. That Tree estimates that A11134 formed around the year 1450:
Hartley Branches under that formed at a later date. For example, FTDNA says that A16717 formed around 1650:
This date follows closely the genealogy of this branch:
These are the YDNA testers under A16717.
It would stand to reason, that other Hartley Branches formed around the same time as A16717 in the 1600s:
I drew an arrow to FT225127 where my brother and I and two other Hartley Lines are. The Nutter Line will be added in that same area.
Summary and Conclusions
- The new Nutter BigY test shows that he is in the A11134 Branch, a Branch formerly held only by Hartleys
- Nutter has two Private Variants which defines his own private line
- Nutter forms a fifth branch under A11134. However, three of these branches are not named yet and won’t be named until they get matches withing those branches
- My guess is that these branches formed in the 1600’s and represent an explosion of the Hartley surname
- My interpretation is that this Nutter tester had a Hartley ancestor probably in the 1600’s.
- The next step is to see the Nutter BigY results added to the FTDNA Time Tree. I don’t know if those results will make a change to the date of A11134.
