Welcome to Touhou Answers. What would you like to know?

Kaguya Houraisan and Toyohime and Yorihime Watatsuki are all Lunarian princesses. Further more, Toyohime and Yorihime are distantly related to Eirin Yogokoro, and used to own Reisen Udongien Inaba. There is no official word on how closely the Watatsukis and Kaguya are related by blood, although it seems likely that they are, unless the Lunarian royal family is extremely strange.
