The protagonist called Connor in Assassin's Creed III has the birth name Ratonhnhaké:ton. He is a Kanien'kehá:ka man whose English name, Connor, is used more often during the game's American Revolutionary setting.
Ratonhnhaké:ton grows up in the village of Kanatahséton before seeking training from Achilles Davenport. He joins the Assassin cause while trying to protect his people and navigate the conflict between the Patriots, the British, and the Templars.
Haytham Kenway is Connor's father and the game's opening playable protagonist, which makes the names easy to confuse. Edward Kenway is Haytham's father and Connor's grandfather, while Achilles is Connor's mentor rather than his birth identity.
