If a clan consists of men, women and children they all must have the same last name (e.g Senju/Uchiha)... in order to keep their bloodline pure they musn't "mix" with outsiders. So then in that case wouldn't there be some cases of incest? What if a brother and sister marry each other and have kids? Then in a way they're keeping the bloodline pure..
