My father Edmund Adolf Hemmersbach whose father was Frank Hemmersbach, whose grandfather was Peter Hemmersbach had an uncle by the name of Henry. My dad said nobody knew where he was for about 25-30 years. My dad said his father got a letter sometime in the 30's or 40's from South Dakota that said he was working on a farm there. All the years through his life he was never married. That is all my dad can remember. My dad also had an uncle Peter Hemmersbach. He lived in Norwalk, Wisconsin. They farmed there. His wife's name was Theresa. They had 7 or 8 children. Does any of this help you out? Please get back with me.
