There's a statue of him here http://ejournals.library.vanderbilt.edu/ameriquests/viewarti...
I'm not in the states - I live in Nova Scotia Canada. My ancestors are Bouchers from Quebec and so is my husband a boucher (a very distant 7th cousin)
I'd love to see your pics!

Here are pics of the first home of Timothy Boucher - he lived in a cave http://www.genealogy.com/users/d/e/m/Timothy-Demonbreun/inde... (Check the links on this page at the bottom)

I'll find more pics and post them later today
