Considering Naruto had only recently found out that the 4th was his father (Pain Arc) does this also imply that he knows nothing of uzushiogakure and his clan? We've come across several characters in the Manga/Anime that are all of the Uzumaki clan, including Tsunade herself (on her mothers side) and thus I can only assume that he's unaware. With that being stated, would it be too farfetched to believe that we may find out about his clan's history in the New Era? (If the third series becomes a reality)
