Mahabharata Adi Parva Chapter 63:7

Mahabharata Adi Parva Chapter 63:7 The eldest of them was Yudhishthira. And Yudhishthira was born (of the seed) of Dharma (Yama, the god of justice); and Bhima of the wolf's stomach was born of Marut (the god of wind), and Dhananjaya, blessed with good fortune and the first of all wielders of weapons, was born of Indra; and Nakula and Sahadeva, of handsome features and ever engaged in the service of their superiors, were born of the twin Aswins. And unto the wise Dhritarashtra were born a hundred sons, viz., Duryodhana and others, and another, named Yuyutsu, who was born of a vaisya woman. And amongst those hundred and one, eleven, viz., Duhsasana, Duhsaha, Durmarshana, Vikarna, Chitrasena, Vivinsati, Jaya, Satyavrata, Purumitra, and Yuyutsu by a Vaisya wife, were all Maharathas (great car-warriors). And Abhimanyu was born of Subhadra, the sister of Vasudeva through Arjuna, and was, therefore, the grandson of the illustrious Pandu. And unto the five Pandavas were born five sons by (their common wife) Panchali. And these princes were all very handsome and conversant with all branches of knowledge. From Yudhishthira was born Pritivindhya; from Vrikodara, Sutasoma; from Arjuna, Srutakirti; from Nakula, Satanika; and from Sahadeva, Srutasena of great prowess; and Bhima, in the forest begot on Hidimva a son named Ghatotkacha. And from Drupada was born a daughter Sikhandin who was afterwards transformed into a male child. Sikhandini was so transformed into a male by Yaksha named Sthuna from the desire of doing her good. "In that great battle of the Kurus came hundreds of thousands of monarchs for fighting against one another. The names of the innumerable host I am unable to recount even in ten thousand years. I have named, however, the principal ones who have been mentioned in this history.'"
