A quick search of Ancestry.com did not turn up these people that I found in an old graveyard. These stones are very weathered and difficult to read in places. Perhaps this info will help someone.

Cemetery: Land of Rest
Location: Town House Road, Swanville, Waldo, ME

David Kimball, d. Jun 17, 1815, age 68; two small stones with letters SMB (?) and H (or M) R

I live 3000 miles from this cemetery and do not have any other information. If you do know who they are, please post for anyone who may need the info.
