Genesis 36:40-43

"And these are the names of the chiefs that came of Esau, according to their families, after their places, by their names: chief Timna, chief Alvah, chief Jetheh, chief Oholibamah, chief Elath, chief Pinon, chief Kenaz, chief Teman, chief Mibzar, chief Magdiel, chief Iram; these are the chiefs of Edom, according to their habitations in the land of their possession. This is Esau, the father of the Edomites."

The apparent inclusion of women's names, Timna and Oholibamah, as titles of certain chiefs shows that the chief took his title from the tribal mother in some cases. That this list does not exactly correspond with that given above presents no problem, for it probably represents the chiefs at a later time than that of the earlier list. The unifying of the tribes under the names of Timna and Oholibamah indicates this.
