I know this is an old post but maybe this would be helpful.
I have an Edward Bemis (1869-1923) buried in Glenwood Cemetery in Littleton, NH. Married to Eva M. Hunt 1878-1922, second marriage). I also have pictures I have taken at the cemetery.
If you are still interested please e-mail me at firstname.lastname@example.org
and I will be glad to forward them to you.
