This tree shows a third Big Y sample for a Flynn family and a fifth Big Y sample for a Morrissey family. I-Y4665 is very typical of Ireland, especially central-western Ireland. The I-Y4665 Flynn family is one of dozens of Flynn families in Ireland, and probably many Flynn families in other haplogroups are much larger. There are also several Morrissey families but maybe the I-Y4665 Morrissey family is the largest Morrissey family.

Thanks for the tree. Currently about half the Morrisseys tested would be downstream of I-Y4665 and include Morrisseys from Tipperary, Limerick, Kilkenny, Waterford and Clare. A rough TMCRA for this group would be about 600 to 800 years ago. The other Morrisseys comprise a variety of unrelated R1b haplotypes and two are unrelated I1.
