My fathers name of "Dargin" was said to have been changed after they came from Ireland to the USA. I believe they settled in Ohio or Illinois. Supposedly, the name was changed from Dargan to Dargin. The descendent name tree looks like this: James Dargin (me) -> David Dargin -> Richard Dargin.David Dargin was born in 1898; my grandfather Richard Dargin's birthdate is unknown to me. I am new at genealogy -- can anyone provide me some clues to most likely ancestors of Richard Dargin.
