I was just going over some records of mine. My husbands grandma was Concetta Reitano and his grandfather was Gaetano. They came from Lipari. I do not know the year they were married but they were both born in 1886. He came to America around 1900 and then went back to Lipari and married her and brought her back to U.S. They had 2 childern Bart and Nancy born in 1914 and 1916. Since your father didn't know them I was wondering if they could be his parents. Sorry it took so long
