Analysis of information sources in references of the Wikipedia article "Bhagiratha" in English language version.
The story of Bhagiratha's birth to two women occurs, as far as I know, only in texts produced from the fourteenth century onwards in Bengal. Other manuscripts of the Sanskrit Padma Purana, in the Devanagari script, and other Puranas too relate that Bhagiratha was born in the regular way to his father, Dilipa. As is standard in patrilineages, these latter texts do not mention his mother's name.
