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)

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
