Iain, I am in absolute agreement with you on this.
Presently some of us from Clan Donnachaidh are now transferring the M222
results for all surnames of the project into Exel to have a look at
phylogenetic trees using at least 2 or more analytical methods.

I suggested to John some time back that it would be good to gather the
M222 data from all the designated Scottish Clan projects and run them
simultaneously as one large group, not just one project at a time. I
think this would be very useful.

From the little bit of research (and it certainly has not been
extensive by any measure) on surname acquisition with-in Scotland, there
were a variety of ways surname use evolved.

It seems that early on the son's took on the McC, Mac, SON etc.
(Duncan linguistically is supposedly a Saxon derivative used in the
Anglicization process) of the given name of the father; ie if the
father's given name was Robert, Robert(son), Mc Robert, Mac Robert,
etc. There are some good sources to better explanations available.

People also acquired their name by taking on the name of a chieftain or
a renowned hero even if not blood related; taking on a name as suggested
such as many who stood with Bruce were allowed the honor of carrying the
name Robert(son).

Some were required to take on a name -- ie there are histories
suggesting that Robertson(s) often would change their surname to fly
under the radar when the English were breaking up the clans -- Other
stories say explicitly that some Robertson(s) in certain Scottish
environs were required to change their names to McC; there are other
stories which claim explicitly that McCs on Isle of Bute were required
by the English to change their names to Duncan.

And of course once patrilinear (sic) surname use was the norm, unless
required to change name as seems to be the case in some instances, the
surnames followed blood lines. Blood line surname use, however, was a
bit late in the game.

So in short it is rather a mixed up mess, and if nothing else perhaps by
looking at the clans member databases at a whole, perhaps we will see
more clarity into which groups and/or individuals were genetically
related to who.
