Okay, so I did some experimenting and found that when I interupt the villager's moving to bury the dead, they just go back to burying the dead.
Now I just jostled them a bit...I didn't put them on another task or anything. Just moved them to the side or let them try the robe.
And Arnie was right about the roster and cemetary. Actually, I hadn't thought of the headstones but by the time I figured out to let them move closer my graveyard was already full.
