Hi, Colin,

I am M222 and I agree with Sandy, that the earliest known ancestor
locations could be misleading, especially of the M222 group, as migration
between Ireland and Scotland has been going on for the past couple of
thousand years or so, since long before surnames came into use, and fair
numbers of M222 can be found in both of those places. The trouble is that
family records often do not reliably go beyond a few hundred years or so,
and often far less than that. So, it seems there could be statistical
limits on the available genetic data, at least until some ancient corpses
could be found and tested, perhaps "The Buried Bog Men of Ireland and
Scotland" or something like that.
