Hi! Can anyone tell me how to pin down what branch of the Dwyer clan my great-grandmother came from? Her name was Mary Dwyer, and she married my great grandfather Thomas Rochford. He came from Buolick., Co. Tipperary, and that is all I know. With such a common name, I don't know where to start to find out anything about her. Thanks for any help. Mary (yes, I come from a long line of Irish Mary's!)
