Okay, the Shinobi Compendium about the Otsutsuki Lineage summarizes / repeats the stuff about the Otsutsuki arriving in search of the Divine Tree's fruit, Kaguya eating the fruit and gaining chakra, and her twin sons "dividing the clan" between the earth and moon, with Hamura taking leadership and migrating the clan to the moon while Hagoromo remained behind to preach Ninshu.

It also confirms that the Byakugan was passed down from Kaguya to Hamura and, after an extremely long time, was eventually inherited by the Hyuga Clan. If I'm reading this correctly (small, blurry, hard to read), it basically says that the founder of the clan and subsequent generations have been extremely focused on preserving the kekkei genkai, which is the source of their strength.

Toneri's profile states that he's the last survivor of the Otsutsuki Clan and has been living on the moon in solitude. The Otsutsuki clan had been dwelling on the moon, watching over the sealed away Gedo Statue for a millenium. Not a lot new in his profile, basically just says he wants to carry out the wish of his ancestors and punish mankind, and that he wants to take a bride and walk hand in hand while destroying the earth, more or less.
