Exactly, which is why I'm hunting for more definitive info from the lovely helpful people here
I'm thinking maybe I should move the tombstone to a public cemetary, then go there & use the "move home" option I've read about - after moving the family to their new house of course! Just not sure if the "move home" option will send it back to it's original location or the family's new digs. For the moment I'm keeping the family put in the old house until I find a solution...even though I'll have nowhere to let the 2 youngest kids sleep once they pass the toddler stage!
