Ha, searched the internet just now and found this old post from you.
"I would appreciate any information of Otto Hamann, a grocer/mercantile store owner in the village of Unity, Clark
County, Wisconsin circa 1900-1925. His only known sibling
was Ida (Hamann) Schulte, Town of Colby, Clark County,
Wisconsin. His parents lived in Centerville, Trempealeau County, Wisconsin before Otto's move to Unity."
In another post you say the wife of "your" Otto was Ruby.
On first glance it looks as if I'm listing a different Otto. Regardless, I'll go ahead and leave my findings posted as is. But clearly we can now see you have lots of information on Otto and you aren't really searching for "any information." Instead, you have a specific gap of knowledge you wish to fill. What is it? Share all you have, such as his parents names, his date of birth, etc, each time you post a querry about him, and also include links to past discussions if relevant. (We assume that your gaps are whatever you don't post.)
I hope the forum will continue on with the hunt, after you chime in with more of what you know. Thanks very much!
