Hi Mary ellen I would like a copy of your database.
My grandfather came over to the uk from Castlebar (?) when he was "very young". I believe he was christened Patrick but he was Richard John when he died in 1955 (aged about 77). He was never sure of his birthdate and work over retiring age before discovering his mistake. I understand that his mother's maiden name was O'Haggerty.
As you can see I have an interesting conundrum on my hands.
