At the time of the first hokage and Madara Uchiha we know there was no leaf village being that they founded it. Where the individuals who founded the village from the fire country or another hidden village. Where was Madara from also. Its said that madara was descended from the Hyuga clan. If madara was around at the begining of leaf then Hyuga must have been around prior. Which village or country do you believe they are from.
You may be able to come to conclusions by the jutsu they use. If they weren't brothers I would think the second hokage from the village of the mist etc.
What do you guys think.
