I am looking for information on my grandfather Bartholomew Delea B: 19 July 1863 in Riverstown, County Cork, Ireland. I have been unable to locate any information about his parents/ siblings, or any other records prior to him coming to America. It's my understanding that when he arrived in America he changed his name to Delea. Previously it was Dunlea, or D'Lea or something similar to that. I appreciate any help.
