The Kate Crotty you sent me was indeed my grandmother. Her mother was a Catherine Ahern who married William Crotty in 1858 at a place called Carrigtwohill in County Cork. My question now is this: is the above named Catherine Ahern related to the Ahern(Margaret) that you are researching? I do not own any reference CD's, books or papers to look further into this.I do subscribe to Ancestry.com, but haven't had a good deal of luck locating people. If you have sources I would be willing to pay you for your services for looking up more info for me.
I think I have seen your name on Crotty Forum which is used lots by Gerry Watts of Florida.I have some stuff he sent me but it was not the same Crotty family.
