Genesis 36:26

And these are the children of Dishon; Hemdan, and Eshban, and Ithran, and Cheran.

Genesis 36:26 belongs to the account of Esau and the nations and descendants that sprang from him. It comes ten or eleven years after Jacob rejoicing under God's blessing at Peniel, after his meeting with Esau and coming in peace to Shechem, and after the destruction of Shechem. It follows the revival in his family when they put away idols and God blessed Jacob and renewed His promises, after Rachel's death and Benjamin's birth, after Reuben's sin, and after the account of the sons of Israel. It follows the death of Isaac at age 180, when Esau and Jacob probably met for the last time.

At this time Jacob was about 109 years old, Joseph was 17, and Benjamin was a small child two to four years old.
