I lost contact with my father a year after I was born, he is down on my birth certificate as James Paul Ruddy, born in the Irish Republic, I know he was born and lives in County Mayo *modsnip*. I do have my parents marriage certificate as well, he is 26 years old and they were married 1990, so that would put his birth in 1963/64. I've paid the 20 Euro to the Registry in Roscommon, they literally could not find any record.
I know his own father was Patrick Ruddy, and believe his mothers first name is Anne *modsnip*
Anyone have any suggestions or help, I've tried all the usual sources, findmypast, familysearch etc. Ancestry is giving me no hints, I literally have a dad that has no traces anywhere!
