The main storyline's continuity of Red Dead Redemption and Undead Nightmare seems to indicate that all Stranger Missions (except for 'Remember My Family'), and Undead Nightmare's main storyline (except for 'A Civilized Man'), would all happen before 'The Last Enemy That Shall Be Destroyed'. Regarding chronology: Although the player may complete most Stranger's Missions at any time (once they are available), as well as the DLC missions.
The player must complete 18 of these missions, excluding 'I Know You', to achieve 100% Completion. Listed below are the 19 Stranger side-missions featured in Red Dead Redemption.
