I need to find my uncle that is on parole to I can find my dad:/

You can't really find out that he is on parole or where he is. You can check your states ( or his states) prison system records, it may show when he got out of prison and what county he was convicted in. ** give you an idea of where he may have moved back to

Spend $25 US dollars and get access to sites that do criminal backround checks.

That is an amazingly easy method of finding, or at least getting an idea of where to start looking for, anyone with a criminal record.
