David, I've looked through all my McAdory material and find nothing on your Chambers McAdory.

Google produced a hit on Chambers McAdory at http://books.google.com/books?id=nkoUAAAAYAAJ&pg=PA656&lpg=PA656&dq=Mississippi+%22Chambers+McAdory%22&source=bl&ots=3y2xoE6GZB&sig=D4G6uCo4uz4CuAp3rJLxsa3wW3U&hl=en&ei=ZRdaS8PiOJCXtgeAzdmkAg&sa=X&oi=book_result&ct=result&resnum=1&ved=0CAcQ6AEwAA#v=onepage&q=McAdory&f=false

and a second hit at http://genforum.genealogy.com/mcashan/messages/5.html

Google "Chambers McAdory" and "Mississippi" and you will get 10 - 15 more hits
