Let me start with what I am sure of: I have the 3 Aug 2006 Wis State Journal Obit for Clara Hericks MLSNA [1910-2006], widow of John MLSNA [8 Mar 1901-7 Jul 1992 from SSDI]. I also have a copy of the 18 Jan 2009 obit for one of their sons, Kenneth [1939-2009].
I believe that this John Mlsna would be the son of Joseph & Wilhemina Mlsna as shown in the 1910 census of Jefferson, Monroe, Wisconsin. I think the same Joseph & Wilhemina appear in the 1900 Census of Greenfield Twp, La Crosse, WI but of course, John has not yet been born here.
Is any of this of interest/use to you?
