Have Names Ready. Find the names of your Italian ancestors who originally traveled to America by boat. Talk to your oldest living relatives to verify your ancestors' names and any information (such as the region or town in Italy from which they may have originated). Importantly, be aware of prior spellings of last names, spelling variations, dialectical spellings, and Americanization of both first and last names. For example, your great-grandfather Louis likely emigrated with the name Luigi first. Other examples (Leonardo = Leonard, Adamo = Adam, Joseph = Giuseppe, Mary = Maria). Keep in mind that variations of names and spellings exist in different Italian dialects. For example, my last name "Longo" was actually an Americanization of the Italian surname "Luongo." Ancestry, very usefully, shows search results for individuals with similarly-spelled names. Many first and last names are common, so
don't assume the first person you find is your relative. Find unique information that definitively proves the individual listed was your ancestor, such as approximate birth date, names of sons or daughters, and destination.
