I notice you said you tried to get information from a geneaological society. Did you try the Henry County Geneaological Society? Here's a link to their website:

Perhaps you can contact them with your questions. I Googled "Richard Debeir Illinois" and found several people by that name in Illinois. Perhaps you could try that, too.
The population of Munson Twp is only about 500, if that. It's completely rural -- no towns. There is at least one cemetery that I know of. I don't know the name of it (it's at the top of a hill with pine trees, and it's very beautiful and peaceful there), but it's so old that the road that used to lead to it from the highway is now little more than a cowpath.
The site of one of the many Black Hawk battles is marked by an inscribed stone on the side of the highway. I always marvel at the place when I drive by -- it's just empty rolling fields. Hard to imagine that Native American tribes fought there. (Actually, they fought all over that area for years over broken treaties and/or broken promises from the French, British and Americans.)
Good luck in your search. Let me know if I can help in some way.
