Does anyone have relatives of Frederick Kelm in the Waukesha County, Wisconsin area? b. Jan 1853 in Germany, married 11 Sep 1879 to Katherine Fehl in Waukesha County.

Searching for information on him, plus his children:
Agatha b. Apr 1884, married an Andrew Wessner on 27 Dec 1902,
Arthur Kelm b. Nov 1886, married Amanda Magedanz b. Mar 1893
Agusta Kelm b. Mar 1891
Adolph Kelm b. May 1893.

Any help would be greatly appreciated.
