I'm basing this on appearances and what little info we got on the Otsutsuki. Assuming, the whole main/branch house system existed around Kaguya's time. Kaguya would obviously be from the main house as she was the leader of the clan, i'm gonna go out on a limb and say Momoshiki is also from the main house based on his royality like robes and "lazy rich" type personality. Kinshiki seems to be from the branch house as his attire resembles a guard, him being able to conjure chakra weapons enhances this possibility even further. Kinshiki could've been a personal guard to momoshiki, possibly raised him. Also Kinshiki seems to have a stronger loyalty to Momoshiki than to Kaguya as he addressed mMmoshiki with honorifics and not Kaguya when they arrived on earth despite her being a clan's leader. Anyways, what possibly made Momoshiki defect from the clan was that he became envious when only kaguya got to eat the chakra fruit.

Onto Momo's departure, this envy aspired Momoshiki to leave the clan along with Kinshiki(Possibly others) to search for chakra fruits for themselves. Maybe Kaguya knew only the shinju on earth could bore a chakra fruit so she knew they would come back to steal her own chakra. Thoughts?
