I was wondering if anyone had a source on Sokon "Bushi" Matsumura and his real name before it was changed. I know it was supposed to have been Kiyo, but I have heard from a few that it may have been longer than that and that Kiyo was the only thing brought forward. Also, Satunuku "Tode" Sakugawa is known for teaching Matsumura. Yet there is nothing else mentioned about the Sakugawa family. Are there still Sakugawa's in Karate? Were any taught by thier reletive Tode Sakugawa?
