My great grandmother was a Katherine Koenen b. about 1840 in Prussia d.1/8/1933 in Houghton, MI. She married Nicholas Kutscheid 11/10/1857 in Holy Cross Catholic Church in Calvary, Wisc. (The marriage record shows both of them as being from Koblenz. The witnesses were Lambertus Kutscheid and Lambertus Kraemer) On her death record her parents are listed as Simon Koenen and Anna Kaiser. Does she seem to fit with any of your ancestors?
