Thekillman, you're not getting my point. The manga only gave a vague description of how the two clans are related. There are different ways the two clans can be related and still fit the vague description. What I'm pointing out is how things the manga said can be perceived as mutually exclusive. If Senju and Uzumaki are strictly cousins, they have a shared ancestor, be it Asura or one of his descendants, in a more recent time. This would mean Senju and Uzumaki became their own clans independently. However, with the manga saying Nagato is an Uzumaki, and of Senju lineage, it would mean the Uzumaki clan branched off the Senju, and as such, every Uzumaki would be of Senju lineage, something I don't think has been said anywhere. No other known Uzumaki was said to be of Senju lineage. What I believe to be the case, despite not clearly being said in the manga, as others have pointed out, is that Senju and Uzumaki appeared independently, instead of the Uzumaki branching from established Senju, but remained close, with a few interclan marriages along the way. This way, there are "pure" Uzumaki, and Uzumaki with Senju ancestry, and probably also "pure" Senju, and Senju with Uzumaki ancestry.
