Charlotte, My understanding is that the Quakers in the early and mid 1700's didn't place headstones on graves. Starting in the very late 1700's or early 1800's they started using grave markers (although it was frowned upon to put anything more that a simple stone on a grave). An example of Quaker cemeteries with markers is West Milton, OH. There are many markers from the early 1800's when they first migrated from NC to OH. Dave Sloan Colorado Springs, CO.
