Coppa of Forio Dischia

I'm looking for information on the family of Galliano Coppa and Immacolata Sacchetti. My father was their son Vittorio Coppa who emigrated to Australia in 1954. He was married to Brigida Patalano and divorced in 1966. I have tried to get information through the local church and municipality but without luck. I know members of both families emigrated to Rhode Island And thought someone there could assist me in my search.

With thanks
