It's not clear if they split from another or from a different precursor clan or something else entirely. This is definitely not true as the sage was said to have several disciples...and clans could have easily arisen from them. The relation between the clans is the chakra resonance left by hagoromo.well Ketsuryugan which has been still left unexplained(which is lot similar to Ranmaru's KKG which was able to negate byakugan which is why I personally believe that they are breeds which were formed inorder to resist okutsuki and their descendants.);
