Hello Carpenter Cousins,
A recent email asked if there was a genetic difference between the two William Carpenter
immigrants. Indeed there is.
Based on 67 Y-DNA markers tested, we provide the following paragraphs on our Carpenter
Cousins Y-DNA Project web page in the discussion of Group 2 & 3.
‘Based on this now-confirmed discrepancy, along with the originally discovered difference
at DYS464d, and the additional difference at DYS413a, we can state with 95% confidence
that the most recent common ancestor of the two groups was more than 2 generations before
the immigrants and less than about 20. Therefore, the DNA testing has very nearly ruled
out the often-repeated claim that the Williams were first cousins. The most likely
estimate is about 7 generations before the immigrants, but that is a very rough estimate,
and the 95% confidence interval is a more reasonable description of what the DNA is
telling us.
When project participants began extending to 111 markers, some new candidate discriminants
turned up among the 35 new markers. (Note that FTDNA included DYS635 in this panel, along
with 8 others we already had from other labs.) However, now that seven members of each
group have upgraded, these new candidates have all been ruled out.’
...
Summary of discriminants between Groups 2 and 3:
DYS464d (13 to 25 set)
Group 2 = 16
Group 3 = 17
DYS413a (38 to 67 set)
Group 2 = 21
Group 3 = 22
DYS635 (68 to 111 set)
Group 2 = 23
Group 3 = 24

I also attach a jpg image of a FTDNA TiP report comparing its results to the traditional
model used by the Carpenter Cousins Y-DNA Project. For those not receiving attachments,

I am happy to answer any questions.
I wish all of you a Merry Christmas!
