John Gill Commentary 1 Chronicles 1:38

"And the sons of Seir: Lotan, and Shobal, and Zibeon, and Anah, and Dishon, and Ezer, and Dishan." — 1 Chronicles 1:38 (ASV)

Ver. 38-42. And the sons of Seir
This man and his posterity were not of the race of Esau, but are mentioned because they were a family into which Esau, and a son of his, married, and whose possessions he and his obtained. The account from hence, to the end of (1 Chronicles 1:42) is the same with (Genesis 36:20–28) , with some little variation of names.
