I saw a tombstone at the City View Cemetery in Union City, TN for Sarah Thompson, born 1847, died February 1915, also on the stone was incribed:
Sweet Home Chamber 2718
Poplar Bluff, MO
There is a symbol at the the top of the stone that is faded,with the letters T, M and A.
Any information on Sarah Thompson and this Poplar Bluff, MO connection will be appreciated.
