Tokugawa Ienari
Matsudaira Katahiro was the younger son of Matsudaira Kataoki and became "daimyō" in 1806 at the age of four on his father's death. In 1813, he was received in formal audience by Shogun Tokugawa Ienari and given the courtesy title of "Higo-no-kami". This was changed to "Sakonoe-gon-shōshō" in 1816. He was wed to Moto-hime, the 15th daughter of Tokugawa Ienari, but died in 1822 without any heir. This ended the line of direct descent from Tokugawa Hidetada begun by Hoshina Masayuki, the first "daimyō" of Aizu.
