Genesis 25:1-4

Abraham married another wife, whose name was Keturah. She gave birth to Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah. Jokshan was the father of Sheba and Dedan. Dedan’s descendants were the Asshurites, Letushites, and Leummites. Midian’s sons were Ephah, Epher, Hanoch, Abida, and Eldaah. These were all descendants of Abraham through Keturah.
