Family Trees

I'm trying to research my family tree. It's very difficult as  I have little information on which to use and it makes me angry that every website claims to have the information that I want....for a price. It's my freaking history. Shouldn't I be allowed to have it for free? Is it this hard for everyone, or is it because I have a convicted member of the Mafia as a  deceased grandfather? I found his FBI file, but stuff is blacked out. I did discover from which region of Italy my ancestors hailed, which is cool, because if I'm going to live there, it would be interesting to see. Or not. I don't know. What am I really looking for? Do I think if I go to this town in Italy all these people will be walking around looking like me?
