Likely a variant of Canaan, meaning lowlands or merchant.
Cainon is a rare masculine name most likely derived from the biblical place name Canaan. In the Old Testament, Canaan refers to the land promised to the Israelites, etymologically linked to the Semitic root for lowlands or the trade of purple dye. It may also be used as a modern phonetic variation of names like Cannon or Keenan.
