I was adopted by step dad. I know my biological fathers name but can not find him
I guess I am the result of a fling my mom had with a guy in the Air Force in Washington State in 1964. When my mom went on public assistance and they looked up my dad I guess he went to court to argue that he was not the father. Her new husband officially adopted me in 1965. I don't know if my biological fathers name was ever listed on the birth certificate. Anyhow I want to find out my family medical history, DNA etc, satisfy curiousity and I am 44yrs now. I know his name and I have searched and searched but I am not having any luck finding him. Have any suggestions on how to find him? His name is Frederick Dufour he would be in his 60's now I am guessing, and he would have been in Washington State in the air force at Madigan during spring/summer 1964. (I was born February 1965)
