Matsudaira Katamori
In 1822, the Hoshina-Matsudaira line became extinct with the death of the seventh "daimyō", the 15-year-old Matsudaira Katahiro, and was succeeded by Matsudaira Katataka, who was a sixth cousin (twice removed) and a member of the Takasu cadet branch of the Mito-Tokugawa collateral line. Katataka died without heirs in 1852 and was succeeded by his grandnephew, the famous Matsudaira Katamori, one of the final supporters of the Tokugawa Shogunate.
