Are there any Free sites where you can look people up for information like marriage, death, criminal ETC?

Information a site like Ancestry would pull up or better for Free.

Thanks.

You can try this site
Pennsylvania Counties Birth Certificate, Death Record, Marriage License and More (A) (http://www.vitalrec.com/pacounties1.html)

Or type in your county and court house official site
And I think you have to click on row offices to get a page something like this
Allegheny County Row Offices (http://www.alleghenycounty.us/chart/rowoff.aspx)
