1) Most names were NOT bastardized at Ellis Island; families would try to Americanize them on their own. That's how you get several spellings of the same family's last name.
In my family's case, it was the workers. My nono said "Vincenzo" and they said "We'll call you Jim". Ditto with my nana who said "Ignazia" and ended up Nancy.
