Information about a Ship Passenger

I am working in filling the form to obtain the Italian citizenship because of my great-grandfather. I was conducting an investigation and found the ship which brough him to America. His name in Spanish is Higinio Rossi but his Italian name maybe different as many Italians had changed names once arrived America and Caribbean countries. I need as many data from the passenger H Rossi born in 1865. I need to know where in Italy did he born, I mean the reagion and comune.
