Question:

What part of Italy is the name Fontana from?

I'm going to study abroad in Italy next year so now I'm interested in tracing my origins. I only got as far as what country they were from on ancestry.com. I have no idea where to search next. Any suggestions? Or maybe someone knows where the name is from? Thanks guys!

A lot of this info was extremely helpful. Thank you for all the links and info. Now I see I'll have to contact the Jersey City court b/c my GG grandfather was naturalized in 1892. Thanks so much everyone!
