My grandfather always liked to half-joke that Al Capone was his 'cousin'. I found out that Al Capone's mother came from Angri, in Campania, where my grandfather's father immigrated from at the turn of the century.

I'm wondering two things:

1) How small, population wise, was Angri around 1900?

2) Is it possible my grandfather's "joke" was actually true, that there was some relation?
