The Mahabharatha kula-Parampara narration begins with Pracheta.
Pracheta had 10 sons and they all married one woman, Marishi. Marishi was the daughter of the woods because she had been brought up there. Note how Draupadi is not the only woman to have married more than one man?
Marishi gave birth to Daksha Prajapati, the son of all 10 Praachetas.
Daksha's wife Veerini gave birth to a 1000 sons but they all left thanks to Narada's suggestion to them that they did not know the world yet.
Daksha's eldest daughter Aditi was married to Kashyapa and she gave birth to the Adityas. Kashyapa also had the son Vivaswaan (Surya) whose sons were Yama and Manu A(laso called Shradda deva and Vaivaswata Manu).
Manu (who is credited with creating Manavas) had 10 children (later had more)- Ikshavaaku, Vena, Dhrushnu, Narishyanth, Naabhaag, Sharyaati, Prushadra, Kaarush, Naabhaagarishta and Ila.
Ila was both man and woman alternately and she gave birth to Pururava through Budha, the son of Chandra. This is where the Chandravamsha officially begins.
Pururava and Urvashi a son named Ayu, whose son was Nahusha, later to become an Indra. Nahusha's son was the famed Yayati.
