Theze were the chiefs of Eliphaz in the land of Edom. They were the sons of Adah. these were the sons of Reuel, Esau's son: Chief Nahath, Chief Zerah, Chief Shammah, and Chief Mizzah. These were the chiefs of Reuel in the land of Edom. These were the sons of Basemath, Esau's wife. and these were the sons of Aholibamah, Esau's wife: Chief Jeush, Chief Jaalam, and Chief Korah. These were the chiefs who descended from Aholibamah, Esau's wife, the daughter of Anah. These are the sons of Esau, who is Edom, and these were their chiefs. Genesis 36: 15-19 NKJV

The term chief here would most likely be interpreted as "ruler of a thousand." This could also be viewed as clans or military leaders. 

Looking back: Jacob has become Israel and Esau has tied to Ishmael by way of marriage. Both Isaac and Ishmael have become the father's of separate nations.
