I checked out several sources at the archives office. There were a number of “Harris”s, only one William - the woman he married and the date were not of any help.
I checked out all the “Margaret Laubenstein”s who married and there were three: one married Carl F. MERZDORF about 1890; one married Wilhelm NIERODE, 28 April 1878; one married Henry KELLING, 26 Feb 1885.
Perhaps this may prove William Harris did not marry a Margaret Laubenstein in Ozaukee county.
May I offer the following suggestions? Do you know where William Harris is buried? Is Margaret buried with him or with Raw? You need a death date (even approximate). Have you tried the State of Illinois on-line data base? http://cyberdriveillinois.com/departments/archives/idphdeath...
If I can be of further help please don’t hesitate to contact me. --Carol
