Since we know that R-M222 is a sub branch of Haplogroup R-P312 (same as
R-S116), and since that haplogroup is broadly distributed in Central and
Western Europe, it is a safe bet that ancestors of the Irish and Scots M222+
came originally from Europe. But that tells us nothing about the time when
that happened or even if the M222 mutation occurred first in Europe and was
later carried to the British Isles.
That would lend some credence to O'Rahilly's basic theory that the Connachta
or northern goidels in Ireland could have been relative latecomers to the
island. By latecomers he meant they weren't in evidence in the tribes of
Ptolemy's map, circa 150 AD. or by his corrected date of ca. 300 BC. It also could
help explain some of the apparent R1b1c7 (sorry, I'm still stuck on that old
term) matches on the continent (they daughtered out possibly leaving a few
strays).
<Simply because the signature is found so strongly in Northern Ireland and
Southern Scotland today, it is most probable that the MRCA lived in that
area. But that does not mean the original M222+ individual lived in that
area.
I wonder if there's any way via DNA analysis to determine if the latest
MRCA lived in either Ireland or Scotland? Could they have been in both places
at about the same time?
I guess this wouldn't really make much difference except for the Nial 'of
the Nine Hostages' thing.
