Thanks for the reply. Is it worth paying $350 to have one of those Italian family sites go find all the naturalization documents? Or is there an easier or faster way?

Also, the 1920 census says that he immigrated in 1902 and was naturalized in 1905. I thought it took a minimum 5 years to naturalize?

I believe I actually probably don't qualify, but was hoping someone might be able to tell me otherwise. All my great grandparents came over from Italy. As I understand it I can only follow my line down from my great-grandfathers and they had to still be aliens when my grandparents were born ...
