My grandfather Harry Donald Richter Jr was born on 6-22-1933. His parents were Harry L Richter whom was around age 24 and mother was Irene Viola Nyman around age 20. They were married in Chicago around September 22nd 1932. My grandfather was left on a farm when he was around 8 years old and never saw his parents again. The family on the farm had the last name Moore? On his birth cert it lists his parents address as 820 Waveland Ave Chicago. It also says his father may have worked at a brewery. This has been an unsolved family mystery for us for many years. My grandfather has passed and we desperately wish to know his history. Any help is appreciated.
