I am from Boston, and looking for Regans in Rahine,Parish Schull/Ballydehob. According to the missing Irish persons listed from The Pilot of 1864, a Michael Regan, son of James Regan of Rahine/Raheen, and sister Mary Driscoll(nee Regan)were looking for missing brother Michael Regan. Michael was the older brother of my grt, grt grandfather Joseph Regan. They came to Boston in the 1850's.
I wonder if you could contact me. I too am interested in learning more about the Regans of Rahine and Ballydehob.
