About Switchboard: I was looking for e-mails. Home addresses are good and that "Baldassare" is almost surely my relative, as probably "Vito" is, but can you figure me sending letters to all of them, with them answering? That would be a lot of money. I'll probably do with these two, however.
Tried Lycos - I already tried by myself and none of those addresses work. How the hell they make an index? Actually, 90% of the addresses I found, both in Italy and in the U.S., don't work. Probably old ones; but don't they ever update?
I think I'll find something with the links you people gave me, but now I should be studying. And another problem is that, if people who receive my e-mail, it doesn't automatically mean they'll answer! (No one did till now, even if I granted no commercial purpose and was very kind in writing).
