Mbh 1.94.4b

And Dushmanta had by his wife Sakuntala an intelligent son named Bharata who became king. And Bharata gave his name to the race of which he was the founder. And it is from him that the fame of that dynasty hath spread so wide. And Bharata begat upon his three wives nine sons in all. But none of them were like their father and so Bharata was not at all pleased with them. Their mothers, therefore, became angry and slew them all. The procreation of children by Bharata, therefore, became vain. The monarch then performed a great sacrifice and through the grace of Bharadwaja obtained a son named Bhumanyu. And then Bharata, the great descendant of Puru, regarding himself as really possessing a son, installed, O foremost one of Bharata’s race, that son as his heir-apparent. And Bhumanyu begat upon his wife, Pushkarini six sons named Suhotra, Suhotri, Suhavih, Sujeya, Diviratha and Kichika. The eldest of them all, Suhotra, obtained the throne and performed many Rajasuyas and horse-sacrifices. And Suhotra brought under his sway the whole earth surrounded by her belt of seas and full of elephants, kine and horses, and all her wealth of gems of gold. And the earth afflicted with the weight of numberless human beings and elephants, horses, and cats, was, as it were, about to sink. And during the virtuous reign of Suhotra the surface of the whole earth was dotted all over with hundreds and thousands, of sacrificial stakes. And the lord of the earth, Suhotra, begat, upon his wife Aikshaki three sons, viz., Ajamidha, Sumidha, and Purumidha. The eldest of them, Ajamidha, was the perpetuator of the royal line. And he begat six sons,--Riksha was born of the womb of Dhumini, Dushmanta and Parameshthin, of Nili, and Jahnu, Jala and Rupina were born in that of Kesini. All the tribes of the Panchalas are descended from Dushmanta and Parameshthin. And the Kushikas are the sons of Jahnu of immeasurable prowess. And Riksha who was older than both Jala and Rupina became king.
