Robin, according to the volumes published by GCGS, the cemetery at Pleasant Garden Methodist does not have any markers currently visible for Frederick Fentress (d. 1874) or his son Frederick (d. 1887). They were listed on one of the readings done by a local DAR chapter (they don't say which one), according to the notes. But in 1986 they could not find a marker for either man. I know it's a frustrating situation.
