I agree what Kakashi stated was that it was rumored that the Uchiha originated from the Hyuuga Clan. In turn the SG was rumored to come from the BG.
He is also known for stating that the RG was just a mutation of chance.
Now let's exam these things shall we?
1. S06P's( form here on out he will be referred to as Ralph) face has never been shown completely or his clan revealed. WHen he is shown it is in reference to the Juubi which in turn shows the SG/RG eye(s).
2.IF Ralph's clan of Origin IS/WAS Hyuuga(the oldest known clan) then it would explain his chakra mastering. He very well could have been the first to be born with the BG. That being said the Uchiha deriving from the eldest brother ALSO solidifies the relation to the Hyuuga.
3.The RG was passed through Ralph to both his offspring. Seems that with the recombining of the DNAs, RG occurs. I wonder, what would happen combining Uchiha with Uzumaki/Senju? IF Ralph was a Hyuuga then that clan's current line is the purest DNA you could find of him.
I still think that the Uzumaki maybe older than the Senju just had less fame. I mean, yeah they were well known but not like the Senju & Uchiha. Basically I think the youngest son had two off spring. Older started Uzumaki, younger started Senju.
