I found out that my Grandfather William Pusch AKA Bill Pusch had a child with a woman in Germany after WWII. He was stationed in Africa and Germany during the war. many years ago my Aunt received a call from a man claiming to be my grandfathers son and I guess she hung up on him. I would like to find out who this person is and make contact with him. Does anyone have an idea how I would go about doing this? Thank you for your help, Gerald Pusch Jr.
