In Assassin's Creed III, Haytham Kenway is the father of protagonist Ratonhnhaké:ton.
Haytham opens Assassin's Creed III as a playable character in eighteenth-century Britain and colonial America. He is introduced as an Assassin, but the story reveals that he is a leading Templar. His relationship with Kaniehtí:io, a Kanien'kehá:ka woman, results in the birth of Ratonhnhaké:ton, who later adopts the name Connor for use among English-speaking colonists.
Father and son occupy opposing sides of the Assassin–Templar conflict during the American Revolution. Their encounters are therefore both political and personal. Haytham's position also makes the Kenway family unusually divided across generations and organizations.
Haytham is not Edward Kenway's father; Edward is his father. Ratonhnhaké:ton is also not simply Haytham's successor within the Templars. He becomes an Assassin under Achilles Davenport and fights against the Templar cause his father supports.
