The marker reveals little about Daizy Harner (d. 1878), but look closely: It tells us her cause of death.
Daizy (Daisy?) was almost certainly a young child. Not only does the small size of the marker (measure it in inches, not feet) suggest she was a child—perhaps an infant—when she died, but so does its badly weathered carving. It is almost certainly a broken rosebud.
