In our surname project we apparently have independent mutations involving
DYS449 (31>32) in three lines, and two mutations in DYS389ii (30>29) in two
other lines, all having a common ancestor in the mid-1600's. The ancestor
was one of the sons of the immigrant, who came from England in 1638. The
ancestral 31 is inferred because all the other lines from this immigrant
have that value. The number of generations is at least 8, but the exact
number is uncertain because these particular haplotypes come from the
Sorensen site, which does not show living individuals.

Another interesting factoid is that there are 10+ haplotypes (again, with
Sorensen there might be duplicates) some of whom differ pairwise on as many
as 5 markers. If we didn't know better, we might think it was unlikely that
they had a common ancestor only 8-10 generations back.

The kicker is that this family is not coming from the undifferentiated mass
of R1b, but G. Out of the founder population of immigrants to New England
in the 1600's, how many were G? considering the pool they came from is now
(and presumably was at the time) less than 3% of the total population of
England?
