Matsudaira Katamori
Teru was initially adopted to become the wife of the future heir of the Aizu han. However, Katataka's fifth daughter, Toshihime was born in 1843, and although physically weak, grew up, and took over this role. In 1846, she became the adoptive sister of Matsudaira Katamori, who was adopted by Katataka to marry Toshihime and become the heir of the Aizu han.
