Ekanamsha

[4] Many "kinship triads", depicting Vasudeva Krishna, Balarama, and their sister Ekanamsha have been found in the Mathura region, which are stylistically dated to the early centuries of the Common era.

[7] Another interpretation of her name is that the goddess Yogamaya came to be known as Ekanaṃsha because she was born of one part (aṃśa) of Vishnu himself.

Traditional According to S. C. Mukherji, a modern scholar, in the Harivamsa, Ekanamsha is identified as a shakti of Vishnu as the goddess of Ekadasi, having descended as the daughter of Nanda to protect the baby Krishna from Kamsa.

[8] In the Harivamsa, she is represented as sister of Vishnu, due to which she is offered the epithets Vimala Devi and Yogamaya.

Though in other versions the baby girl is carried to the Vindhya mountains, in this text, she stays with Vasudeva and Devaki.
