Cut peach in half; remove and discard pit. Put peach onto a square of aluminum foil, both halves facing up. Put a large pat of butter or margarine into each hollow. Add brown sugar, making sure to cover the open peach halves. Add marshmallows to hollow. Put peach halves together, add a little more brown sugar, wrap aluminum foil around it, making sure it's completely covered. Put into the coals just inside the fire. Cook for 3 to 5 minutes.
