Here's Andy DeSimone's grandfather, Guiseppe Nacca from the 1920 census. The family lived in Carroll Gardens at 27 Cheever Place. The whole block was Italian except for the Fitzgerald's. Guiseppe was a longshoreman and just about everyone
on the block depended on the neighboring docks (about 6 blocks away) for employment. Here's a link to a previous post about Eli Wallach, a Jew who grew up just a short walk away at 166 Union Street.
