The Markandeyapurana has a story on his life before becoming the sixth Manu. His name was Ananda and he was the son of Anamitra. When he was small, a cat carried him away and put him in the cradle of King Vikranta’s child. The cat also took away the king’s child. He grew up in the palace as the prince, but once announced that he was not the king’s son and left the palace to meditate. Finally Brahma appeared before him and blessed that he would be reborn as the sixth Manu.
