I don't know if elder child of hamura is a hyuga or not, but I believe hamura is the ancestor of that 2 clan.
Well that's not a very symmetrical family tree/pyramid with the Uzumaki being overall fifth clan with a connection to the Otsutsuki Family. Unless we bring in Chatte's theories onto the table and speculate that Sakura's clan is related to the Kaguya Clan, that is. I suppose Hamura's elder child would be the Hyuga Clan ancestor while the younger child would be the Kaguya Clan ancestor, right?
Sakura herself is two individu who has a pink hair(the other one is tayuya, even thought I see it as red). Hagoromo has pink hair, perhaps It come from fruit side effect or his father has red/pink hair.
Uzumaki has big stamina and some member has the abilities to materialize chakra in the form of chakra chain.
I think, hagoromo ninshu allowing the creation of kekkei genkai. And perhaps secret jutsu.
