Looking for Birth Mother in Germany

I am finding out many of us born in Germany were adopted to american military. I just started looking for my birth mother, Christlel Schmidt. I was adopted in 1960, put in an orphanage at birth. I had a German friend tell me recently that in the 50's, if you were born illegitimate, as I was, the german government took the children away. I do not know if this is true, but it inspired me to seriously look for my mother. I always wondered why relatives didn't take me in. Good luck to all in your search!
