I've been researching CACCIATORE for several years. My Grandmother was Rosalia Cacciatore, born in San Biagio Platani, Agrigento, Sicily. Her father was Gaspare. I've not found a birth record for him in S. Biagio, and have reason to believe that his father Sebastiano was born in San Stefano because a death record indicates that Sebastiano's father Giacinto was born in San Stefano.
San Stefano is a village near San Biagio Platani. Many, many families from both villages were recruited to work in the cigar factories in Tampa's old Ybor City. My grandfather and his brother and sisters worked there before going to Colorado to work in the coal mines and eventually settling in Chicago. The reason I tell you all this is that there is a website with birth records from a midwife in Ybor City from the early 1900s.http://www.faithfuldeliveries.com/midwife.htm

for your great grandmother under her maiden name. That's how I found many of the records I was seeking for family
Once you determine what village they were from in Sicily you can get films with birth, death and marriage records at the Latter Day Saints Family History Centers (there's probably one in your town or one nearby). http://www.familysearch.org/Eng/Library/FHLC
These records are in Italian but there is a help sheet available for translation. I need to get films for San Stefano to search for my great grandfather Gaspare Cacciatore.
Also there is a new book out by Tafford Cole that illustrates and translates Italian records. It's available on ancestry.com.
Good luck with your search.
