The old graveyard contains a unique stone with a carved depiction of body snatching, marking the theft of Mary Stevenson (1767–1822) by James McNab, the local gravedigger who had buried her two days earlier, on 16 November 1822, aided by a friend, Daniel Mitchell. The body was passed to John Forrest, for dissection. The two men were caught, but released due to legal technicalities and a riot ensued. Mary's body was reburied and the stone carved to mark the strange event.
