Am doing some ancestry research and have a image of a page from the S.S. Belle of the West that left Port Said (Cairo) in May of 1946. My Dad was a passenger. How can I obtain more information? My Dad is the only name on the page titled, "LIST OF UNITED STATES CITIZENS" because he was born in the U.S. in 1910 but at some point, his Mom took him back to Italy (she died shortly thereafter and he was orphaned).
