Genealogy

Has anybody experience of genealogy websites? I have a hankering to find my ancestors before it's too late. I did join a website once before, paying for the privilege, only to find that I had to buy tokens to look at the documents I found.

 I don't mind paying to join, but when I put in a name and date, they would find loads of results ans expect me to pay to look at each until I found the one I was looking for, if it was there at all.

I would be grateful for any advice. Ta
