Family Tree DNA is recalculating Big Y results

I only knew about this because of an email that began..

Dear Big Y Customers,

We are still recalculating your Big Y results. We apologize for the delay and appreciate your patience during this exciting update to Big Y.

We anticipate this taking approximately 7 more days. During this time, you will continue to see “Results Pending” in the Big Y section. You will be notified by email once your results are processed and ready.

Below is a refresh on the changes we are implementing. We can’t wait for you to experience the new Big Y!

I will note that I got this email 10 days ago, so once again, Family Tree DNA has underestimated the effort required, in terma of how long this will take.

There is extensive discussion of the issue on Anthrogenica. Overall, I think the best approach is to be patient. People have noted the recalculation has changed terminal SNPs in certain cases. The standard for having a unique DNS change has also been adjusted. Again, dirty details are discussed in depth in the Anthrogenica thread.

Yfull results and YDNA calculations at the 50% level.

Yfull emailed me and my results are in. ¬†Yfull calls me R-PH2278, which is their labeling of Z39300. This is a slow outfit, and there will be more results in coming months. I’m especially looking forward to these guys digging out the STRs they can fetch from the BIGY data.


I also spent just a bit of time looking at the 50% limits of a Y37 test. Artie and I are a 36 of 37 match, and his terminus is Cap William Myers, through George. 36/37 at the 50% confidence average 4 generation apart. Folks who test like us are about equally as close or closer than 4 gens, and 50% past that point. Now, the point to remember in this kind of calculation, is that George Myers could be Charles’s father in this deduction. We cannot exclude him as a potential father. George is 23 years old when Charles is born, and if we assume a Northampton PA birth, then yes, George fathering Charles is possible.

So, the 4 gens are: George, William, William’s dad, William’s granddad. At the 50% mark, Charles Sr is, compared to William Sr, his grandchild, his child, his nephew, or his first cousin, once removed.

At this point, there is still plenty of regular genealogy and genetic genealogy to do.

Big Y tested. R-BY15581. Z38300+

I had decided that if my work gave me a bonus, I’d have the BIG Y done. It was frustrating not having a known terminal SNP, and I wasn’t sure what else I could do to get there. Just, BIG Y is expensive. In this case, I’d say it was worth it.

Turns out the TX Myers Y-DNA is rare. We were the first family with a BIG-Y test that was Z39300 positive that claimed continental European origins. All others were from the Britain/Scotland/Ireland cluster. So that means we’re pretty unique, and that we changed, in a small way, the Y-DNA tree. The data are here. And that small portion of the tree changed when our data were added.

We’re not the only family with this cluster. There are close STR matches on familytree that likely have it as well. Some are found in the Feichts of Pennsylvania, and perhaps other families as well.

That’s the good news. The bad news is that genetic genealogy is illegal in France and Germany, and so we’re not going to be given help from overseas. It’s going to require more grunt work on our side of the Atlantic.
