The Leinster cluster of folks has done a lot of work and testing and have
interesting historic background from my home area, although I'm not one of them.
John McLaughlin describes the Leinster Modal and some of the background.
http://clanmaclochlainn.com/leinster.htmHe says the Leinster cluster's "main matches in Ireland are to be found in the
ancient kings and chieftains of Leinster, Kavanaghs, Kinsellas and O'Byrnes plus
a lot of other typically Leinster surnames. Several modals for this cluster can
be found on Ysearch (B9NW4 is one)."
I looked at the Leinster modal and tried to pull out the key off-modal (WAMH) marker signature. The most common lower panel markers I pulled out are >389/1 <448. The ">" just means greater than the modal (WAMH) and the "<" is less than the modal.
The following is the list of confirmed R-L21* that I found in FTDNA and Ysearch:
McKee unk unk unk 4VDRN
Ford Ireland Munster unk VNFX8
Carmack unk unk 2c2g PAMN9
Beatty Ireland Connacht 2c2g T78VB
Beattie unk unk 2c2g EZRDK
Aspel Ireland unk 2c2g 6Y9G8
D'Arcy Ireland Leinster 2c2g PXDEB
McHale Ireland Connacht 2c2g S7EM6
McLaughlin Ireland Ulster 2c2g 3JJR8
Fitzwilliam England Isle of Man 3c1g A7STZ
Downing England unknown 2c2g 4PSCK
Cienfuegos Spain Iberia 2c2g 59JDM
Stephens Scotland Strathclyde unk 62TQZ
McKee, Ford & Stephens have neither 67 markers tested nor 464x (that I know of),
but everyone else on the list has. Those with 67 markers are also <442 >557
>446 so there is a pretty clear signature amongst a group of R-L21* folks. Does
anyone knows if McKee, Ford or Stephens are upgrading to 67? It'd be interesting to see if they truly fit? If they look like they do, they might also consider the 464x test.
As best I could, I gleaned from the 464x project those results and those that
tested, other than FitzWilliam(Quilliam) were the unusual 2c2g value for 464x.
Is it hard to know for sure the 464x results so anyone who sees errors in this,
let me know.
One more point. Remember this is a cluster within a subclade, but just a
"cluster." I'm not sure if Cienfuegos is in this group, although I can't say
for sure. He is 2c2g though, right? I'll post another topic on this shortly.
