Aṃśu (Angshu) was the son of Purumitra of the Jyāmaghar (Jyamaghar) clan which descended from the Yadu clan. He was the father of Satvata (Satwata), who founded the Bṛiṣñi (Brishni) Andhaka clan. But the Bengali version of Viṣṇupurāṇa (Vishnupurana) has identified him as Puruhotra’s son, Aṃśa (Angsha).
