It is well known that Draupadi is wife of Yudhishthira.
Wikipedia and several other sources say that there is another wife to him and her name is Devika. The following excerpt from Chapter 95, Sambhava Parva, Mahabharata clarifies it.
Besides these, Yudhishthira, having obtained for his wife Devika, the daughter of Govasana of the Saivya tribe, in a self-choice ceremony, begat upon her a son named Yaudheya.
My doubt : Are there any other wives for him other than these two and are there any more references to Devika in any scriptures other than that provided in Mahabharata?
