Arthur is the nephew of Harold and Lillian (king and queen of far far away). It is confirmed that Arthur's last name is pendragon this may mean that Harold and Lillian's last name is pendragon. This also means that fiona's last name may be Pendragon. When shrek was young his father tried to eat him when he was young his dad may have left after this. Everything about his mother is unknown he may not know her. As shrek has no last name he may have taken fiona's. This would make him Shrek Pendragon.
