Hi there,
I run the Hourihane YDNA project.
If you have an eligible male relative patrilineally descended from Patrick Hourihane (that relative's last name now being Brien), and you are interested in using genetic data to see how he is related to other men also patrilineally descended from other Hourihanes from the area, feel free to email me at hourihanedna@pobox.com and I'll point you to some resources.
Best wishes,
Susan
