<Chuckle.> They're not in the same patrilineal line, of course! One is my
mother's mother's sister's son, and the other is my mother's mother's
sister's daughter's son. But as I mentioned, their ancestral villages are
less than 100 miles apart in southern Poland, and as far as I know their
patrilineal lines were both under serfdom for centuries; so their genetic
distance from each other was quite remarkable.
At 12 markers, their GD was 8.
At 25 markers, their GD was 13.
At 37 markers, their GD was 27.
At 67 markers, their GD is 36.
By the way, I should also underscore the very unusual nature of the other
end of this new world record. YGHJ3 of Scotland is a truly rare and unusual
R1a1; indeed, he is actually more unusual than my cousins. Despite an
ancestry from one of the most genetically sampled countries on earth, he is
a GD of 32 from his nearest neighbor at 67 markers. Indeed, I suspected
that he was not truly R1a1 but rather something like R1a*, and so I took the
trouble of looking up his surname project and verifying that he was
SNP-tested for R1a1.
But here's the real kicker: His surname project is not nearly so sure that
his ancestry is from Scotland at all:
His patrilineal ancestor simply appeared in Maryland in the 18th century,
and the attribution to Scotland on his Ysearch entry appears to be merely a
supposition. So here's the unconventional question:
Could he be a rare example of an R1a1 whose patrilineal ancestor came to
America long before Columbus, and perhaps from central Asia rather than
Coincidentally--or not--the same small surname project includes two men
predicted to be in the rare haplogroup F. Again, no paper trail to Europe.
One of them, or a relative, is on Ysearch as 9RTFQ and is SNP-tested to be
Hg F. He lists his ancestry simply as Unknown. But at least he, on
Ysearch, has plenty of near neighbors of varying surnames who are also F or
Unknown: VRZH5, 69E8U, EE9GD, KTEBX, 7TTRV, 8TGQ5, M4JWA, BHNGT, JJDQQ,
P42YH, 8ARVS, EUBQ2, U5X24, K3ZE7, YEES6, BR8VD, S6EXD.
