Genesis 36:14
And these were the sons of Aholibamah, the daughter of Anah the daughter of Zibeon, Esau’s wife: and she bare to Esau Jeush, and Jaalam, and Korah. And these were the sons of Aholibamah, the daughter of Anah the daughter of Zibeon, Esau’s wife: and she bare to Esau Jeush, and Jaalam, and Korah.
The chapter in which this genealogy stands is given wholly to Esau and to the nations that sprang from him. Its place is ten or eleven years after Jacob rejoiced under God's blessing at Peniel, after his meeting with Esau and his coming in peace to Shechem, and after the destruction of Shechem. It follows the revival in Jacob's family when they put away idols, when God blessed Jacob and renewed His promises, when Rachel died and Benjamin was born, when Reuben sinned, and when the sons of Israel were listed. It follows also the death of Isaac at the age of 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.
