I am searching for the Giarratana from Alimena, Sicily too. My dad went over to Sicily last year and found that there are just a few of them left over there. Apparently they changed the spelling of the last name when they arrived over into the U.S.. The way we spell our last name is Girratono. But my dad seems to have found gravesites in Sicily of some of our ancestors. Giovanni Giarratana and Maria Giarratana (Maria was born Nov 11, 1915 and dies Jan 1, 199?). His fathers name was Tony Girratono (he is now deceased).
This has to be the same family, because my dad said unless they came here they stayed in Alimena.
Let me know and hope this helps a little. I am still trying to get more info on Giarratana's.
