I found a Charlotte Gunsch in 1920 in Wayne County, Michigan, 9th Ward, Detroit. She has two daughters, Mildred, age 6, and Ruth appears to be under 1 year old. It's (illegible) 12's, or so many months old of a year. Charlotte states she's married but no sign of a man. It also says she has no occupation. She and the daughters were born in Michigan (why did you think Chicago?) and her parents were German. The girls' father was born in Michigan as well. For some reason, the enumerator put both girls as in school, but I sincerely doubt the younger one was in school I couldn't find her in 1900 or 1910 on Heritage Quest. Maybe someone else could help you there or, if you are primarily interested in Mildred, maybe someone could do 1930 for you. I don't have access to that. Joan in Illinois
