I have a Katherina Fritsch/Fritch, born July 1, 1878, in Maple Grove, Manitowac County, WI and married John Schiessel.
She was the daughter of Carl/Karl Fritsch/Fritch (from Austria / Bohemia / Germany / etc)(1840-1915) and Catherine Zeaniger. Carl's mother (Margaretha) has a prayer card which indicates that she died in Cincinnati, OH; while I have notes I haven't been able to verify which say she died in Maple Grove, WI. It is possible that the entire family is from Cincinnati, OH and not Maple Grove, WI.
If this matches up, let me know. I have more info.
