I don't know the "beginning" of the posts for this either. In my catalog of
varieties of R1b I have the small Irish one with 8,9 at 459 and the
13,13,15,17 at 464. I believe the 8,9 at 459 resulted from a single-step
mutation from the rather robust 9,9 population of R1bs which is present most
everywhere (9,10 is the dominant modal). But this variety with unique 459
and 464 has a definite Irish connection, with such surnames as Lynch, Casey,
Cusic, Hogan, Bryan, Bryant, O-Dea, Burke, and now your Dorsey from Ireland.
