The recent Busby study, which is totally independent of how many Americans
have tested with FTDNA, reports M222+ with a frequency of 133/1394 (9.5%) in
UK & Ireland. Outside of UK & Ireland it reports M222+ at a frequency of
If we consider only Western Europe (but outside of UK & Ireland), we find
If we consider England on its own, we find 7/509 (1.4%). However, if we
exclude NW England (ie Carlisle, which was under Scottish control in the
days of yore), we have 2/462 (0.4%).
So if we were sit and wait for England and French M222+, we'd have an awful
long wait on our hands. For all practical purposes it simply doesn't exist,
or perhaps more accurately, exists in such a small quantity that it will
never affect the M222+ modal.
There is of course still a possibility that FTDNA data is biased towards
Irish DNA, but I'd suggest that much Irish DNA comes from Scotland anyway.
Here's an interesting and relevant article:

Further to Sandy's comment, I'm not sure that we gain anything by
pursuing the "age" of M222 at the moment. We have both insufficient
evidence (unless we go down the Bill Howard track) and what is clearly
an unbalanced swag of data. In my observation, the American need to find
roots earlier than the immigration data allows has led to the
possibility that the proverbial red herring is affecting the noses of
The fact is that we have a lot of Irish data (from American immigrants)
that inevitably drags the M222 modal toward their genealogical history.
My own surname study is a good example of this phenomenon. I have, on
the face of it, about six out of sixty with paper connections to
Scotland, a couple to England, and the rest without verifiable
paperwork. Most went from Ireland during the famine or to seek religious
freedom, and most claim unknown heritage. And clearly, most genetically
M222 descend from the same family at about the time of the foundation of
the American colonies. So, my family modal is leaning towards them. I
therefore can't use that modal as a founder modal pre the migration era.
The modal has its uses for comparative purposes, but does NOT
necessarily represent the haplotype of the founder because of that bias.
Let's wait until we have more French, English and Scots participants
before we draw too many conclusions. What intrigues me is the reluctance
of Brits in particular to contribute their DNA. What real of imagined
historic events have led to this reluctance?
Compliments of the Season to all
