Mbh 13.4.1

"'Bhishma said, "Listen truly in detail, O son of Pritha, how in olden times Viswamitra attained to the status of a Brahmana Rishi. There was, O foremost of Bharata's descendants, in the race of Bharata, a king of the name of Ajamida, who performed many sacrifices and was the best of all virtuous men. His son was the great king named Jahnu. Ganga was the daughter of this high-minded prince. The farfamed and equally virtuous Sindhudwipa was the son of this prince. From Sindhudwipa sprung the great royal sage Valakaswa. His son was named Vallabha who was like a second Dharma in embodied form. His son again was Kusika who was refulgent with glory like unto the thousand-eyed Indra. Kusika's son was the illustrious King Gadhi who, being childless and desiring to have a son born unto him, repaired to the forest. Whilst living there, a daughter was born unto him. She was called Satyavati by name, and in beauty of appearance she had no equal on Earth. The illustrious son of Chyavana, celebrated by the name of Richika, of the race of Bhrigu, endued with austere penances, sought the hand of this lady. Gadhi, the destroyer of his enemies, thinking him to be poor, did not bestow her in marriage upon the high-souled Richika. But when the latter, thus dismissed, was going away, the excellent king, addressing him said,--'If thou givest me a marriage dower thou shalt have my daughter for thy wife.'
