Claim: Matsudaira Yasuhide was born to the high-ranking hatamoto Matsudaira Yasuzumi, a samurai in the direct service of the Tokugawa shogunate, but refused to take the name of Daimyō.
Evidence: Matsudaira Yasuhide was born in Edo to the high-ranking hatamoto Matsudaira Yasuzumi; his childhood name was Mantarō. Yasunao served in a variety of minor posts in the Tokugawa shogunate, before being appointed to the concurrent posts of gaikoku bugyō and Kanagawa bugyō in early 1860. From 1860 to 1861, he was involved in boundary negotiations with Russia, and was a member of the Tokugawa shogunate's embassy to Europe. Matsudaira Yasuhide (松平 康英) (July 16, 1830 – July 5, 1904) was a Japanese daimyō of the late Edo period, who ruled the Tanakura and then Kawagoe Domains. Daimyo (大名, Daimyō, Japanese pronunciation: [daimʲoː (listen)) were powerful Japanese magnates, feudal lords who, from the 10th century to the early Meiji period in the middle 19th century, ruled most of Japan from their vast, hereditary land holdings.
