Searching for Birth Father American Military

Hello, I was born in Kaiserslautern Germany 12/26/1967. I have found my birth mother through Search Angel Leonie Boehmer. My birth mother is Gonul Bayrak and is Turkish and was on a work Visa in Germany at the time she conceived and gave birth. She is unwilling to discuss the details of my birth father. The information I do have is that his name is Richard Dawis/Deweese/Dwees/Dewees/Dwees or Richard D. Weiss He was approximately 24 when I was born which would make him around 59 today. He was an American stationed in Germany when he met my mother. Thank you so much for any information you can provide.
