I am looking for living grandchildren of Emil and Mary Gartzke who lived in Menasha, Winnebago, Wisconsin in 1930. They had at least 9 children, one of whom (Alfred) is the grandfather of my nieces and nephews. I am trying to piece together some family history for them as all of their records have been lost and their father and mother both died when they were young.
Emil was born about 1880 in Germany. Mary was born about 1887 in Wisconsin. Any information is very much appreciated.
