Hi,
A while back, I sent for an obit from the Wisconsin Historical Society files. Copied on the same page as mine, was an obit for "William E. Flack, Elkhorn Druggist 47 years, dies." As yours seems to be the only message on the Flack board that mentions the right county, I thought I would see if this item is of interest to you. The clipping was from the Janesville Gazette & dated Apr 30 1943.
It stated that he was the son of Mr & Mrs James D Flack.
Hope this reaches you or someone who is interested, it's been over 8 yrs since the original posting!!

Regards
Larry
