There are a lot of great resources on the Web for finding your birth parents. This is the one I used to find mine. I like it, because in order for it to work, BOTH parties (parent[s] and child[ren]) have to submit their information. That way, you never have to wonder if the person you get in contact with is really willing to be contacted. http://www.isrr.net/
