This is showing some wide diversity .



Dan, this Gallagher sample (U3GXW) is not R1b1c7. So you can't compare him
to your uncle's sample (92VDK) which is definitely R1b1c7. Apples and
oranges.

I now have 10 Gallagher (and variants forms) DNA samples in my Donegal
spreadsheets. Exactly half are R1b1c7; half are not. There are also at least 3
R1b1c7 Gallagher samples on the Sorenson site. Three more that are not R1b1c7
but I haven't pulled the samples since it's so time consuming.

One thing every R1b1c7 Gallagher sample has in common is DYS 458 = 16
(except for one, DX85V, a Gallagher from Donegal, who has 14 at this marker. I'm
sure DNA experts could offer an explanation for the 14 instead of a 16. The
odd thing is three of the Gallagher samples that do not appear to be R1b1c7
also have the unusual value of 16 at DYS 458 even though they mismatch at
almost every possible R1b1c7 modal value. I have no explanation for this. Except
it might be just coincidence.

What immediately springs to mind is you could have two separate groups of
O'Gallaghers with different origins. Perhaps one Scottish, one Irish? Or a
group that evolved separately somewhere else in Ireland? Maybe the non
matching Gallaghers are interlopers into the Donegal clan? Just because we have
no records of Scottish Gallaghers or Gallaghers elsewhere in Ireland doesn't
mean there couldn't have been multiple origins for the surname.

Look at the Doherty surname. By the time of the Griffith's the surname is
found to some degree in every single county in Ireland. But we know of only
one origin for the surname (Donegal). Plus a possible second origin in the
south (O'Doorty, or O Dubhartaigh). This surname almost certainly was
corrupted into the more familiar Doherty. McLysaght notes the surname became Doherty
in Cork. His map references to the surname include Tipperary, Clare and
Cork. I personally wouldn't be surprised to find some Dohertys native to
Scotland as well. But before anyone takes me to task for that I have to admit I
have no information whatsoever on possible Doherty surnames in Scotland.

The Gallaghers are one of the Donegal families said to have taken part in
the migration to Mayo. There are lots of Gallaghers in the Mayo Griffiths.
But the one sample listing an origin in Mayo falls into the non R1b1c7 group.

The only other thing I see that sets Gallaghers apart is three of five
R1b1c7 have DYS 460 = 12, a non modal value for R1b1c7. One Gallagher sample has
the DYS 447 = 24 noted in McLaughlins and Dohertys. Two have DYS 576 = 17,
another marker value common to McLaughlins.

The Gallagher pedigree splits off not from the O'Donnells and Dohertys but
from the O Muldoraidhs and O Canannans of Donegal, chieftains of Tirconnell
prior to the rise of O'Donnell ca. 1200 AD. The O Muldoraidhs are extinct as
far as anyone knows (O'Donovan said he couldn't locate any in the early
1800s). The O Canannans are probably still around as Canons or Cannons, a common
Donegal surname. But the pedigree of the O'Gallaghers is probably unreliable.
It's much too short in comparison with the O'Donnell and Doherty pedigrees.
All that means is it's not strictly historical. There are no O Muldoraidh
or O Canannan pedigrees which extend much past the 1200s when O'Donnell
became chieftain. Their pedigree was apparently suppressed by the O Clerys, bards
to the O'Donnells. Only one other sept is said to descend from this Cenel
Conaill line, the Mac Giolla Finneins, whose pedigree appears in the Fermanagh
Genealogies. It also compares poorly to the O'Donnell and O'Doherty
pedigrees for the same reason (much too short). The Mac Giolla Finneins held
territory not in Donegal but in neighboring Fermanagh, once claimed by the
O'Donnell chieftains. Their surname supposedly has evolved into Leonard. McLysaght
refers to the surname as McAleenen, McAlinion, McAlindon.

The O'Donnell and Doherty pedigrees, in contrast, are remarkably consistent
in terms of generations and dates. Neither is fully traceable in the annals.
