Genesis 4:17-20

He had sexual relations with his wife, and she became pregnant and gave birth to Enoch. At that time Cain was building a city, which he named after his son Enoch. Enoch had a son named Irad, Irad had a son named Mehujael, Mehujael had a son named Methushael, and Methushael had a son named Lamech. Lamech married two women, Adah and Zillah. Adah gave birth to Jabal, who became the first person to live in tents and raise cattle.
