My Granfather on my mother's side comes from Leonforte, Sicily.His name was Gaetano Riggio, born in 1874, married to Stella nee Casulo. They had Two children when they left italy, Salvatore, and Vincente.They arrived in America on September 1,1907. I wonder if there is anyway I could get more information them, birthdates, birthplaces, etc. I know my grandmother's sister was married to Antonio Argila who left Leonforte some years earlier. I would like to trace my grandparent's roots. Casulo may be misspelled. Thank you.
