Markers in red indicate Irish Type III Y-DNA

The following from Leonard M, Keane, Jr:

QUOTE
I have viewed your website a number of times, as I am one of relatively few persons of Irish ancestry belonging to what has been dubbed (temporarily at least) as "Irish Type-III".

The key elements of that Haplotype are 13-13-15-17 at DYS #464 a - d, and 8-9 at DYS #459 a-b. Like most of your project members, I am Haplogroup R1b, but my Irish Type-III Haplotype seems tom narrow the possibhle area of origin quiter a bit. BUTLER is considered to be of Anglo-Norman origin, coming into Ireland shortly after the Anglo-Norman invasion of 1169.

But your Group 'G' and my own fairly close matches to O'BRIEN, CASEY, CROWE (McEnchruadh), which are all native Irish Co. Clare families, suggests an explanation.

These families have been closely associated with my own O'CATHAIN (O'CAHAN)family, both by marriage and also military affiliations within Co.
Clare, from the late 16th C. through the 19th C.

I suspect this 'G' group of BUTLERs may descend from one or more adoptions of orphaned children from the other Gaelic Irish families associated with them in military activity against the English. The documentation I have gathered suggests there must have been many such children in such dire
circumstances among these aristocratic families which took a leading role in the wars that lasted for centuries with little interruption.

Early in 2006, researcher Ken Nordtvedt, found another small grouping where the ancestral geographical area appears to be predominately Irish, but the haplogroup was quite different from NWIrish. The group has been given the name "Irish Type III" and its distinctive markers where it differs from AMH are:

Irish Type III                    AMH
DYS 439 = 11                    12
DYS 459 = 8-9                   9-10
DYS 464 = 13-13-15-17   15-15-17-17
DYS 456 = 15                   16
DYS 463 = 23                   22

Searches have been conducted in the Ysearch and other STR databases, and nearly 80 haplotypes have been found which relate to this new grouping, within a Genetic Distance, GD, of 10 to the modal. A record with the name "Irishtypethree" and ID, NT4BZ, has been set up in Ysearch database, to assist others in searching for similar haplotypes.

Looking at the ancestral geographical area for this grouping, 80% participants state 'Ireland' with the region of Ulster and the counties of Donegal, Clare, Tipperary, Limerick and Kerry nominated. 15% give England and the counties of Devon and Wiltshire, and only 2 1/2 % each give Scotland or Wales.
