I was trying to run down a Carl Ziebell buried in Union Cemetery, Milwaukee and so worked a bit on looking at Carl/Karl Ziebells in Milwaukee. I do not know if this is the right one I was looking for, but after so much time on the computer I decided to put it up for other Ziebell Researchers:
Karl Ziebell b. Germany m. Wilhelmine 'Minna' Hein Were residing in Milwaukee as early as 1886 Children found: Hedwig Ziebell b. 16 Mar 1886 Milwaukee Meta Bertha Ziebell b. 21 Oct 1888 Milwaukee Emil Ziebell b. 12 Jan 1891 Milwaukee Walter Carl Ziebell b. 22 Apr 1894 Milwaukee Flora Clara Olga Ziebell b. 22 Jan 1897 Milwaukee
Hope this helps someone. Under Wisconsin Births and Christenings on Family Search many of these were misspelled.
