I've just returned from 5 great days in Vicksburg and Meadeville, MS, locating,documenting, and cleaning the graves/headstones of both of my GGGrandfathers on my fathers side, who were both CSA veterans. My question is, I noticed on one of the government headstones the Maltese Cross is inscribed on the head. Was this the common insignia of CSA soldiers? Also, my other GGgrandfathers headstone bears a Christian cross, much like we see today on christian deceased headstones. My question is my GGgrandmother, buried next to him, and who is legended to have been an "angel of mercy" to soldiers during the siege of Vicksburg, has a headstone with the same inscription. This seemed odd as it was exactly like the government headstone my grandfather has. Would this have been common?
