Linda, we keep shifting topics, and here I go again -- I wanted to mention that in the course of some research I'm doing right now, I've run across some new information (new to me, anyway) about activities in the area between White County and the Mississippi River that should tie in to some of your own research.
Right now I'm struggling from information overload, but as soon as I can get all this stuff sorted out, I'll post some information that might be of use to you.
