Mbh 13.85.12b

, Bhrigu and Angiras and Kavi, regarded as Prajapati, are the progenitors of many races and tribes. All are the children of these three. Know this, O puissant hero. Bhrigu begot seven sons all of whom became equal to him in merits and accomplishments. Their names are Chyavana, Vajrasirsha, Suchi, Urva, Sukra, that giver of boons, Vibhu, and Savana. These are the seven. They are children of Bhrigu and are hence Bhargavas. They are also called Varunas in consequence of their ancestor Bhrigu having been adopted by Mahadeva in the form of Varuna. Thou belongest to the race of Bhrigu. Angiras begot eight sons. They also are known as Varunas. Their names are Vrihaspati, Utathya, Payasya, Santi, Dhira, Virupa, Samvarta, and Sudhan was the eighth. These eight are regarded also as the offspring of Agni. Freed from every evil, they are devoted to knowledge only. The sons of Kavi who was appropriated by Brahman himself are also known as Varunas. Numbering eight, all of them became progenitors of races and tribes. Auspicious by nature, they are all conversant with Brahma. The names of the eight sons of Kavi are Kavi, Kavya, Dhrishnu, Usanas endued with great intelligence, Bhrigu, Viraja, Kasi, and Ugra conversant with every duty. These are the eight sons of Kavi. By them the whole world has been peopled. They are all Prajapatis, and by them have been procreated many offspring. Thus, O chief of Bhrigu's race, hath the whole world been peopled with the progeny of Angiras, and Kavi and Bhrigu. The puissant and supreme Lord Mahadeva in the form of Varuna which he had assumed for his sacrifice had first, O learned Brahmana, adopted both Kavi and Angiras. Hence, these two are regarded as of Varuna. After that the eater of sacrificial libations, viz., the deity of blazing flames, adopted Angiras. Hence, all the progeny of Angiras are known as belonging to the race of Agni.
