Ham is named as the father of Canaan after the Ark story.
Genesis 9:18 identifies Ham as one of Noah’s sons and says he was the father of Canaan. The statement appears after the Flood, when Noah and his family have left the Ark. Genesis then narrates an incident involving Noah, Ham, and Ham’s brothers, followed by Noah’s words concerning Canaan.
The three sons named in the Flood account are Shem, Ham, and Japheth. Genesis presents Canaan as Ham’s son, not as another son of Noah. This family relationship is a frequent source of confusion because Canaan becomes important in later biblical history as the ancestor associated with the land of Canaan.
The passage is part of Genesis’s genealogy and narrative, not a modern historical census. Its wording should also not be expanded into claims about all later peoples without considering the different interpretations and uses of the text.
