In Assassin’s Creed III, the character’s birth name is Ratonhnhaké:ton.
He is a Kanien’kehá:ka man from the Mohawk Valley who later adopts the name Connor for easier interaction with colonial society. The game follows his life during the American Revolution and his involvement with the Assassin conflict.
Ratonhnhaké:ton is the character’s Kanien’kehá:ka name, while Connor is the English name most commonly used in the game’s interface and marketing. His father is Haytham Kenway, a Templar Grand Master, creating a central family conflict in the story.
The character is therefore often listed as Connor Kenway, but that is not his birth name. Assassin’s Creed III was released in 2012 and introduced a new historical protagonist after the conclusion of Ezio’s trilogy.
