Yes, Amanda (Benny) is buried in Broken Bow, Okla, by her son and daughter-in-law. Her son was William Wedzel (Bud) Beauchamp. Her marker is gone, you are right. That is interesting about Francis Rodgers marrying A.M. Deaver in 1881. Maybe that is what happened to her. I have nothing. I thought she was Francis Allen Rodgers Self - but maybe she dropped the self. James was older than Amanda,and his name was Rodgers. I heard, but I don't have a source,and I have no verification that a tree fell on Francis and killed her. It may not be true, and it may have been after she married again. I know that she was not living with her parents or children in 1880.
Thanks for the reply!
