John Gill Commentary Genesis 36:26

"And these are the children of Dishon: Hemdan and Eshban and Ithran and Cheran." — Genesis 36:26 (ASV)

And these [are] the sons of Dishon Not of Dishon the son of Anah, but of Dishon the son of Seir, (Genesis 36:21); and they are the four following: Hemdan, and Eshban, and Ithran, and Cheran; the first of these is called Amram, or rather Chamram, (1 Chronicles 1:41).
