Hi Edward:
My Iovino ancesters are from Lercara Friddi, a town in Sicily south of Palermo. I have them there going back to early 1800's. My great grandfather came to New York in the early 1800. One of his sons, my grandfather, changed his name to Iovin (by dropping the "o"); his siblings kept the "o" as far as I can tell. I believe there were a lot of Iovinos in Lercara Friddi: it is still a popular name there. It looks like Angri is in Campania, so I don't know how closely we could be related. I live in Connecticut.
Best,
Jeff
