This is a fascinating story. I suspect we will be hearing more about people
with matching Y DNA profiles (haplotypes) and different surnames as the
database at FTDNA grows. I can only recall one other instance coming up in my
automated RootsWeb mailing list search, COPE / KOZLOVSKY.

Your scenario is intriguing, with some additional circumstantial evidence
about a doorstep baby in the Leighton line plus Allisons and Leightons living
in the same neighborhood. It is certainly POSSIBLE, but I don't think we're
at the stage where we can say how PROBABLE it is.

Logically, you could flip the scenario and look for Leightons in Allison
neighborhoods, too. I checked the FTDNA web site database, and they had only
one LEIGHTON and two ALLISONs listed, so there's not enough data to give a
"modal" (most common) haplotype for either surname. Do you know if the two
Allisons match, and how far back the common ancestor is?

One other thing we could check is the overall frequency of the haplotype.
There's a database for European haplotypes, which is probably about as good
as we can find for New England ancestry. You would need to have the exact
number of repeats for the STRs used at FTDNA. Let me know privately if you
need help converting them.
