Looking for information on Emil Treu born September 7, 1875, in Milwaukee. His parents were Martin Treu and Wilhelmine Olaff. He was married to Mary Jochem on May 15, 1897, in Milwaukee, and they had two children, Emil and Edward. The problem is, around 1917, he disappears from Milwaukee city directories and is nowhere to be found, even in the 1920 and 1930 Censuses! Death records also turned up nothing. Any info is greatly appreciated. Thanks.
