“The clans of Edom are Timna, Aliah, Jetheth, Oholibamah, Elah, Pinon, Kenaz, Teman, Mibzar, Magdiel, and Iram. These are the clans of Edom.”
These are the names of the eleven clans of Esau, so don’t say that Esau had no descendants. Incidentally a few are women, Timna and Oholibamah. Timna was the concubine of Eliphaz, the grandson of Esau. Oholibamah was the wife of Esau. Kenaz and Teman were the sons of Eliphaz. Aliah or Alvah in Genesis might have been a son of Shobal. However, we do not know much about the others mentioned here, Jetheth, Elah, Pinon, Mibzar, Magdiel, and Iram. This is almost the exact same as mentioned in Genesis, chapter 36.
