1 Chronicles 1:24-31

The three main branches in summary: Shem, Arphaxad, Shelah, Eber, Peleg, Reu, Serug, Nahor, Terah, and Abram (Abraham). And Abraham had Isaac and Ishmael. Abraham’s family tree developed along these lines: Ishmael had Nebaioth (his firstborn), then Kedar, Adbeel, Mibsam, Mishma, Dumah, Massa, Hadad, Tema, Jetur, Naphish, and Kedemah—the Ishmael branch.
