Thanks for trying to help. I believe my ggrandfather was in the militia and therefore would not have been eligible for a marker. I think my only hope would be to find descendants of Porter Moore who might have some follow-up on him.
If you have time, I would appreciate any help you could give. My ggrandfather's full name was Powhatan Lefridge Moore. He is listed in the 1860 census in Pike Co. Mo.
