What was Mr. Grave's dying request?

He wanted to be buried in a location separate from where the members he didn’t like had been buried.

He wanted the other members of the Donner Party to eat the flesh of his body once he died, so they could live.

He wanted the group to keep a candlelight vigil for a week after his passing.

He wanted his wife and daughter to burn his remains so the other members would not be tempted to use him for food.
