Hello! I love researching ancestry, especially when it is my own. I read your post after google searching "circo's from carlentini, Italy". My grandmother's (aka- Nana) name is Josephine Circo Fucinaro. In other words, her maiden name was Circo and her father and mother immigrated from Carlentini, Italy to the US and settled in Omaha, NE. I myself grew up in Omaha and know there was a large number of Italian immigrants specifically from Carlentini to Omaha. My Nana's parent's names were Salvatore and Marianna Circo. One of my Nana's sister's names was Rose. After reading your post I couldn't help but think that we have too many similarities not to be connected. Looking forward to hearing if my instincts were correct!
