James M. Campbell, History of Gujarát
“ The Yádavas in Dwáriká.The next Puráṇic legends relate to the establishment of the Yádava kingdom at Dwáriká. The founder and namegiver of the Yádava dynasty was Yadu of whose family the Puráṇas give very detailed information. The family seems to have split into several branches each taking its name from some prominent member, the chief of them being Vrishṇi, Kukkura, Bhoja, Śátvata, Andhaka, Madhu, Śurasena, and Daśárha. Śátvata was thirty-seventh from Yadu and in his branch were born Devaki and Vasudeva, the parents of the great Yádava hero and god Kṛishṇa. ”
