rocanayam ato jata
hasta-hemangadadayah
ilayam uruvalkadin
yadu-mukhyan ajijanat
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Vasudeva, by another of his wives, whose name was Rocana, begot Hasta, Hemangada and other sons. And by his wife named Ila he begot sons headed by Uruvalka, all of whom were chief personalities in the dynasty of Yadu.
