Yajnavalkya is an ancient rishi who is associated with many texts in Sanskrit such as the Shatapatha Brahmana, Shukla Yajurveda and the Brihadaranyaka Upanishad. His discussions with Raja Janaka of Videha are quite well-known.
This Hindupedia page mentions two things about his origins - One that he was an incarnation of Brahma and son of Brahmabahu and Second, he was the son of Devarata. But it also says that there may have been different people of the same name.
I want to know the correct genealogy of Yajnavalkya, the guru of Raja Janaka. I am aware of his two wives Maitreyi & Katyayini but would like to know about his progeny as well.
