I don't know anything about the Fred Oexmann family, but as you can see, my last name is Oexman but spelled with only one N. My great grandmother, Marie Oexmann, still spells her's with two. Most of my family lives in Georgetown and Terre Haute, Indiana. But what gets me is the Larson name; my Uncle Lance is married to a woman, Tammy, who used to be married to a Larson, though i never knew his name. My grandfather and grandmother had 6 kids, 2 boys (Nelson and Lance) and 4 girls (Dana, Robin, Dawn, and London). My grandmother passed away in February of 2005. I just thought that this information might help you piece somethings together.
