In the 1900 US census in District 953 - Chicago Ward 30 - Cook County - Illinois - I found Emil b. Aug 1868 in Wisconsin (both his parents born in Germany) with his wife Viola b. Oct. 1872 in Iowa (her father born in Maine and mother in Iowa). At this time they had been married 9 years and they had only 4 children all of whom were living. Emil was a night watchman. They had Pearl b. 1892 in Iowa, Doran b. Jan 1894 in Illinois, Earl b. Sept 1895 in Illinois, and Myrtle b. May 1898 in Illinois. Their address was 5916 State. I'll forward more info as I find it!
