Timna in the Bible Encyclopedia - ISBE

tim'-na (timna`; Thamna): A conbubine of Eliphaz, Esau's son, and the mother of Amalek (Gen 36:12). But in Gen 36:22 and 1 Ch 1:39 Timna is the sister of Lotan, and in Gen 36:40 and 1 Ch 1:51 a chief or elan of Edom (see TIMNAH (3)).

Gunkel's theory is that Gen 36:12a is a later insertion in P.
