>Does this exclude me from this line of Clancys?
Without other evidence, the only thing you can say for sure is that
you are not paternally related to Paul Augustine Clancy or to any of
the other R-M222 Clancy. It is possible the Clancy of Darty 500 years
ago differ from the Clancy living in that area today. For example,
consider a Jane Clancy who father is R-M222 and living 500 years ago.
She has a son out of wedlock by man who is R-M269 and her family
chases him out of town. The boy is raised as a Clancy but one to two
hundred years later who would remember these details? The descendants
of Jane would be R-M269 Clancy living amongst R-M222 Clancy and so far
as anyone knows they are all family. A similar thing probably did
happen before so that even Jane's time the Clancy were a mix of
haplogroups. FYI, in the smgf.org database is a Clancy whose ancestor
is Michael P. CLANCY b. 1852 Galbally, Limerick, Ireland and he is
predicted to be R-M269.
