How long does someone have to be in the ground before it is ok to dig him up?
I've got a few in my family lines, who died in the 1750's, that were "dug up" by archaeology students at Wake Forest University, in the 80's. It was a "Strangers Cemetery" though; no one knew it was there at the time, the roads had changed, and the village was long ago abandoned. I guess the answer depends upon whether the grave site is tended to in any way. "Unknown' burial sites appear to be fair game.
Depends. Does he have any cool stuff buried with him? I like cool stuff.
It depends on how much whites victimized your ancestors and/or your descendants.
