徳川家達
On November 9, 1867, Tokugawa Yoshinobu, the 15th and the last shōgun of Tokugawa, tendered his resignation to Emperor Meiji and formally stepped down ten days later, returning governing power to the Emperor, marking the end of the ruling power of the Tokugawa shogunate. By the next year, Tokugawa Iesato (1863–1940, from Tayasu family) was chosen as the heir to Yoshinobu as the head of Tokugawa clan; on July 7, 1884, Iesato became a prince, just like the heads of some of other notable Japanese noble families, known as Kazoku. The 1946 Constitution of Japan abolished the "kazoku" and the noble titles, making Iesato's son, Iemasa Tokugawa, no longer a prince. Iemasa had a son Iehide, who died young, so he was succeeded by one of his grandsons, Tsunenari. Tsunenari is the second son of Toyoko (eldest daughter of Iemasa) and Ichirō Matsudaira (son of Tsuneo Matsudaira), and he is also a patrilineal descendant of Tokugawa Yorifusa, the youngest son of Tokugawa Ieyasu.
