<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.

Ken and All:


I may have kicked off some of the discussions of this unique haplotype, both
on and off the list. You might want to check my personal web page at -:

I'm working on a second page of discussion of this comparatively rare
result. I have found a cluster in a very confined area of west Clare which I
attribute to adoptions/ fosterings of orphaned children of my own KEANE family.
These are BUTLER, O'BRIEN and CASEY with GDs of 4-5 with me. I've found a
number of others above GD 6 spread out from NW Ireland (Donegal) down thru the
Midlands and into the Tipperary/ Limerick/Clare region. This may suggest a
possibly widespread pre-surname tribal group, perhaps now reduced in numbers.

I note the names CUSIC (variant of CUSACK) and BURKE in your list. These
are Norman surnames. Any idea where these specific ones came from in Ireland?

As I have the only known O'CAHAN connected pedigree going back to Ulster at
least to the beginning of surnames (with reservations about the Niall of 9H
part), I have been able to compare it with historical events involving each
of these families leading to a very plausible explanation of adoption rather
than blood descent from any one of them. BUTLER is Anglo-Norman, in Ireland
"only" since after 1170; O'BRIEN is usually of the Dalcassian line (from
Brian 'Boru' - k. 1216), but I don't believe my match falls into that category,
though they are married into my KEANE/O'CAHAN line; CASEY is also married
into KEANE/ O'CAHAN as recently as 1714 in Clare, exactly at a time when
arrangements for fostering must have been made with relatives.
