If you are correct in linking the group of Isles M284 in Iberia to a
migration in recent historic times from Ireland, it would make sense that a
much larger contingent of the major haplogroups in Ireland should also be
found there - unless you are proposing the unlikely scenario of a selective
haplogroup migration. In other words since L21 comprises about 90% of Irish
Y chromosomes, would we not expect to see a much larger number of L21 (or
even its derivative M222) in that region of Iberia than M284? I don't think
that this is the case, but the admins of the L21 and Iberian Projects would
be in a better position to shed some light on the subject. Also, as Father
Oquendo has noted re Puerto Rico, we should also see morphed (spelling wise)
Irish surnames in the same area of Iberia as the M284 is found.
