I also went to that cemetary, and found some of the Pledger names listed. Isaac could be buried there. Oconee Hills Cemetary only has Marshall and Mary Haron, Lemuel and Mary Elliot, Roy Lemuel, and Walter M Pledger Sr. and Kathleen Smith. There is also a Charles Pledger buried in another area but died about the same time as Marshall did. I did notice that there are some Harons buried in Princeton's cemetary. They should be related to Mary Haron, possibly Mother/Father or Brother/Sister? It is also interesting that Princeton's other name is "PLEDGER CHAPEL"
