Anouschka Knauf

My father was adopted in Germany when he was born. There is no other relatives I am interested in anyone who wants to come forward, I was too late to find my father before he died sadly I want to find perhaps some of his living relatives probably un beknown. I hadn’t seen him since I was 3 years old and never saw him again. He lived a happy life in the end and was blessed with a good wife, I was the only child I think. All I know is his birth name was Pixberg first name Steven. I want to know who his mother and father where it’s all I have to build my heritage.
