Genesis 36:2

And Esau took his wives of the daughters of Canaan,.... Of the Canaanites, the posterity of cursed Canaan, most of them were of them, though not all, the two following were, and so those, if different from them in Genesis 26:34, one of his wives was of the family of Ishmael, as after related:

Adah the daughter of Elon the Hittite; according to Jarchi and Aben Ezra, this is the same with Bashemath, Genesis 26:34; and that she had two names:

and Aholibamah the daughter of Anah, the daughter of Zibeon the Hivite; the daughter of the one, and the granddaughter of the other, it being usual in Scripture to call grandchildren children, for Zibeon and Anah were father and son, Genesis 36:24; and the Samaritan, Septuagint, and Syriac versions read here, "the daughter of Anah the son of Zibeon": there are an Anah and a Zibeon who were brethren, Genesis 36:20; wherefore Aben Ezra supposes that these two brothers, or the father and son, lay with the same woman, and it could not be known whose child it was that was born of her, and therefore this was called the daughter of them both. Jarchi supposes this wife of Esau to be the same with Judith, Genesis 26:34; but not only the names differ, but also the names of their fathers, and of the tribe or nation they were of.
