My Great-Grandmother's maiden name was Josepha Cammarata,
she was married to a Carmelo Guastaferro, they
lived in Vallarosa, Sicily, provice of Enna, she
came to this country with her daughter, Salvatrica
LaMarca whose second husband was Raimondo LaMarca,
her first husband was Salvatore Messina. I think
the spelling of her first name might be different.
Could this be a link to your family.
