Like my question is asking, are they marrying their own cousin? I'm wondering this because I remember Obito telling Naruto that Sasuke was his relative in volume 71 chapter 683: I Dreamt the Same Dream. I also remember Madara saying the same thing to Sasuke and Obito, which got my attention.
So according to what I've read in the manga they are saying their blood is all connected which, therefore, makes them all relative? So if they are relatives that make them cousins or something like that? If they do end up being cousins, are they marrying their own cousin? Isn't that kind of disturbing to them or am I wrong and in the Uchiha there are still different family members but have the same last name, which makes them all "relatives"?
