Hello List,
All but 10 markers (39-47) have now returned for Member #160239, the descendant
of Charles CARRICO of Sullivan Co., IN, through his son, Josiah. So far, he is
a 57/67 match with the modal haplotype for the family:

Most importantly, he does *not* bear the mutation from 37 to 36 at CDYb (bright
blue table cells), which means this mutation has happened at least twice,
independently, in the family: once downstream of Charles, through his son,
Basil, and once in or downstream of Thomas Ignatius CARRICO I. We need to test
brothers of Charles G. CARRICO to determine Basil's status with regard to this
mutation:

CDYa and b are among the most volatile of all markers, so the same mutation
happening twice in the same family, while uncommon, is not impossible. We still
have two additional individuals with this mutation: the descendant of James T.
CARRICO of Washington Co., KY, and the descendant of John W. CARRICO of Prince
William Co., VA. While it's not impossible that those mutations also arose
independently, it's more likely that they didn't, so for them things are leaning
in the direction of a connection to Thomas Ignatius I. As always, the testing
of more cousins -- and more markers -- can eventually tell us what the real
relationships are.
While the result just returned resolves the issue of the CDYb mutation for
Charles CARRICO, it leaves descendants of Charles somewhat deflated because he
is apparently going to be a 67/67 match with the modal haplotype for the family,
giving us no clue as to his parentage. If we are going to get the kind of
resolution of relationships that we had hoped for, I'm afraid it's going to mean
we have to "max out" our markers:

I know what I'm asking is expensive, but I hope you will consider that this
testing is something we can do as a legacy for our CARRICOs, because what we do
will benefit all future generations in knowing what their lines really are. I'm
not especially hopeful there is much more "paper" to be found to answer these
questions, so it's DNA or nothing for many of us.
