Hi, i'm also looking for relatives and when i saw your message, i had to know more. I know from what my father once told me, and that was that his parents had 18 children in Licata Sicily, and coz my grandmother was so young when she had them and also ignorant, that some of her children were taken. From that i mean, one or two at birth were taken by others who didn't have children of their own.
I also know that one of my dad's uncles left for the states long time ago, when my father was still very young, and my father was born in 1921, that uncle was never heard of again, apart from one or two letters. I think his name could have been Jiusepe (Joseph). My grandfather was (Alessio Re) all lived in Licata, which is a province of Agrigento in Sicily.
