What web site can you go to with out paying a fee to look up information on someone like birth records, death?

Information on marriages family history back ground checks etc.|||The only way for free is if you work for the city/county/state and have a access to the computers that give you that info but you have to be careful. If you look up someone who has a red flag with their name like if they have a warrant for their arrest then the computer will cross link stuff and let others know that you looked at their name and you will get yelled at since your not supposed to look up people for fun
