I'm trying to find information on my Family in Bonefro, Italy. Grandparents Antonio Porrazzo Born 1879 & Carmela DiStola Born 1889 came to USA in 1920's. My Great Grandfather was Nicola Porrazzo and Great Grandmother was Carolina Lommano. They had 5 children Antonio (my Great Grandfather, Concetta (b.1881), Maria (b. 1889) Rosaria (b. 1885) and Carmela (b. 1892). Do you have any advice as to how I can research them?
