The Wikia Editor wrote: If I were to guess who the Kaguya clan are descended from, I'd guess Asura, since his line seems to produce body-related techniques, whereas Indra and Hamura's lines tend to produce eye-related Kekkei Genkai instead. My guess is either Hamura or a combination of Ashura and Hamura's descendants.

We don't know how many kids Hamura had, it's possible he had more. But it seems that neither Ashura nor Hagoromo had Shikotsumyaku, so i find it more likely that Hamura had it. Seems to me that between the brothers (legendary eyes and all around superb power versus a guy with a byakugan), Hamura otherwise drew the short end.
