Several of my ancestors, particularly military who served in the civil war, were buried, disinterred, and reburied, some along with spouses. Most often, the original burial and marker were removed completely,. The policy on findagrave, as I was told, is not to distinguish the memorials, unless managers choose to explain the situation in the bio. I have one who was interred near the battlefield, disinterred, given a state funeral, buried, disinterred, and buried again. The first burial has no memorial. I don't know of a consistent policy.on wikitree.
