Subject: Re: [R-M222] New M222 Philogenetic Tree

I haven't gotten too far with this yet but I wanted to check on how
McLaughlins and Dohertys fared in Bill's philogenetic tree. The results are
There is one complete segment of this tree (if that's the right word)
composed primarily of McLaughlins and Dohertys, beginning with Kit 105896 Fleury
and continuing until Kit 31706 Doherty. The McLaughlins in this specific
section belong to our Donegal cluster McLaughlins. There are other M222
McLaughlins in the project who do not match this group. Mostly they are
scattered in other segments. My own DNA sample falls into the
Doherty/McLaughlin segment (Kit 75919).
There are a few unknown surnames that fall into this segment, including
Fleury. MacLysaght states this name can be used for O Furey. Next on the
list is Stroup. That is a German surname but the DNA matches the Doherty
modal perfectly. It may be an NPE. Then a Tucker (O'Tougher) from Ulster and
Connacht. This is followed by a Cowan, a McKeon and a Sloane. Next comes
a McAuley. Those names are difficult. I don't know why they fit into the
segment but I was aware of a McAuley with McLaughlin markers.
Next we find a group of McGonigals, Megonnigals. That name can be
Scottish but there are also lots of McGonigals in Donegal. Then comes a Cannon.
It's tempting to think that might be O Concannain, former kingss of
Tirconnell or Donegal prior to the O'Donnells.
A Damnan follows. This is a known NPE.
Then the McLaughlins begin.
Here we find a Slotnick, another known NPE. And a Ewing. This particular
Ewing is in the McLaughllin DNA project because he's a perfect match for
the Donegal cluster McLaughlins.
Then we have a Neel. Possibly O'Neill?
Then a Devanny, a common Donegal surname.
These names are actually interspersed with McLaughlin samples.
There are a few other non matching surnames.
Foster. This is an NPE in the sense that they known the surname was
changed from a Mac name on entry into Canada.
A Slavens. Slavens is supposed to be a Cenel Eoghain surname (same tribe
The last name which makes no sense to me is Forrest.
Mostly I'm impressed that the clustering in the chart placed (most) of the
Dohertys of Donegal and our McLaughlin Donegal cluster in the same
segment. They are two surnames we actually know a lot about in Donegal, both
descended from Nial by different sons. I know there are other samples in our
Donegal cluster that fall outside of this segment, mainly in the next few
that follow in the charts.
I presume the family tree type branching lines in the charts represent the
common ancestor of all in a given segment. It's hard to keep the lines
straight but it looks like an RCC of 20 is indicated. I think that works out
to about 866 years or a TMRCA in about 1145 AD.
That part does not make any sense to me but I might be misreading the
charts. I'll have to check with Bill to get his opinion on that.
There are a lot of Dohertys in this project and stray samples are found
interspersed else where in the charts. I think most of the M222 Dohertys are
related. At least they appear to be when STR modals are involved. So
perhaps this method isn't perfect. But it does seem to have properly isolated
the core of two large surname groups in the project and some at least of
the intervening surnames are explicable in terms of NPEs or possible Donegal
If that's true I'm not sure how reliable this would be for single or just a
few surname examples. I see the Cowans are mostly centered in one
segment; so are the Ewings. McCords mostly clump together.
