Born Feb 24, 1982 Hanover PA

Hello,I am searching for my birth parents. I was born Febuary 24, 1982 in Hanover Pa. I was adopted to a family that lives in Harrisburg Pa. I know that my mother was 18 and my father was 17 and are of German/Swedish descent. The adoption was done through Catholic Charities. I can use all the help that I get on searching for my parents. The adoption agency can only give me medical information or non-identifying information for $200.00 which I already have. Help!
