The default phrasing on the gravestone reads, "Here lies "Mark" Rancher Extraordinaire Rest in Peace", though the name can be changed. In the original Japanese version, if you had connected your Harvest Moon: Friends of Mineral Town to A Wonderful Life (or Harvest Moon: More Friends of Mineral Town to Harvest Moon: Another Wonderful Life), the name of your A Wonderful Life character would appear on gravestone since Harvest Moon DS takes place 100 years after the Wonderful Life's time period. Your Gamecube character has naturally passed away, leaving Pete (Pony or Claire, if you are playing Harvest Moon: DS Cute) in charge of the same farm, hinting that they are a descendant of the player's previous character.
