Consider the following excerpt from Mahabharata

The eldest of Kunti's children was called Yudhishthira, the second Bhimasena, and the third Arjuna, and of Madri's sons, the first-born of the twins was called Nakula and the next Sahadeva.

And the children became great favourites of the Rishis, as also of their wives, dwelling on the mountain of a hundred peaks.
