Iron Grave Markers in Virginia

The Fredericksburg Confederate Cemetery is also the City cemetery and while there I noticed three iron grave markers. I photographed the large pair from front and rear. I guess the large circular recess is to hold a pot of blooms? The frame of one has long since rusted away and the stone plaque now rests against the base. The other is recumbent and forms an ornate border to what remains of the stone. Sadly, I cannot now remember the size of the latter, although it may have been the grave of a small child. If anyone has been to Fredericksburg and remembers it, please let me know.
