Esau took his wives from the Canaanites: Adah the daughter of Elon the Hittite, Oholibamah the daughter of Anah the daughter of Zibeon the Hivite, and Basemath, Ishmael's daughter, the sister of Nebaioth.
Genesis 36:2-3

Adah means "ornament", Eliphaz means "god of gold", and Aholibamah means "tent of the high place". Esau married for wealth and status, not for character. (See Genesis 36:2,10,14.) He followed the pattern of Lamech. When he realized how displeased his parents were with his choice of brides, he married Bashemath, whose name means "fragrance." By her he hoped to remove the stench he had become to his parents, but he was still missing the point.
