i am looking for a site that will allow me to search for familey records like cencis reports birth death and marrage reports for free
Ancestry is the only place I know of that has ALL census records. Many random counties have some. You can also access ancestry (or heritage quest) sometimes for free at your library.
There are thousands of free sites online. However, they are "specialized", not like Walmart of ancestors (all in one place).
If you shift thinking to "the more, the better", you'll start finding all kinds of places.
