Hi,
I'm not connected to the O'Brien family but I have Alice [probably baptised as Mary] Dooley daughter of David Dooley and Ellen Kennedy born 1838 in Bruff. I have a website and the pages for the Dooley and Houlihan family: http://lintywhite.com/houlihan2.html http://lintywhite.com/dooley.html…; Dooleys were in Bruff, Houlihans in Fedamore. Alice Dooley followed her husband William Houlihan to Australia in 1872. William had left Ireland for Australia in 1864 with his cousin Mary Droney.
My father and I have both done Ancestry DNA tests if you would like to look for any match you have with us. My test is Lintywhite and my father's is B.H. . We have our tree connected.
Regards,
Jenny
