Who married Tokugawa Yoshinobu?

Prince Tokugawa Yoshinobu (德川 慶喜; 28 October 1837 – 22 November 1913) was the 15th and last shōgun of the Tokugawa shogunate of Japan. He was part of a movement which aimed to reform the aging shogunate, but was ultimately unsuccessful. He resigned his position as shogun in late 1867, while aiming at keeping some political influence. After these efforts failed following the defeat at the Battle of Toba–Fushimi in early 1868, he went into retirement, and largely avoided the public eye for the rest of his life.
