Does anyone have any advice on how to find out a true last name? My grandfather came from Italy in the early 1920s through Sicily and was supposedly nobility. He passed away when my father was very very young and his last name was changed when he came through Ellis Island. I have no idea what my real last name would be or how to find out where he came from. Supposedly, the original last name was several words, but I also do not speak Italian. I don't care about titles or money or anything like that, I just want to find out where I came from. Thank you!
