Śukadeva Gosvāmī said: From Purūravā came a son named Āyu, whose very powerful sons were Nahuṣa, Kṣatravṛddha, Rajī, Rābha and Anenā. O Mahārāja Parīkṣit, now hear about the dynasty of Kṣatravṛddha. Kṣatravṛddha's son was Suhotra, who had three sons, named Kāśya, Kuśa and Gṛtsamada. From Gṛtsamada came Śunaka, and from him came Śaunaka, the great sage, the best of those conversant with the Ṛg Veda. The Seventeenth Chapter describes the sons of the eldest son of Pururavā named Āyu, [Note: The other sons and their descendents were described in SB 9.15.3.] who increased the ksatriyas, and describes the notables in that line such as Alarka.
