Minamoto no Yoshiie
Minamoto no Yoshishige (1135–1202), grandson of Minamoto no Yoshiie (1041–1108), was the first to take the name of Nitta. He sided with his cousin Minamoto no Yoritomo against the Taira clan (1180) and accompanied him to Kamakura. Nitta Yoshisue, 4th son of Yoshishige, settled at Tokugawa (Kozuke province) and took the name of that place. Their provincial history book did not mention Minamoto clan or Nitta clan.
