However, Nobunori left the Aizu Matsudaira family soon after the Meiji Restoration, to let Matsudaira Kataharu become the heir of the family. Matsudaira Kataharu was Katamori's eldest biological son, born from one of Katamori's two concubines (Saku and Kiyo) after Nobunori was adopted. The family headship then passed to Kataharu's brother Morio, and subsequently to Morio's son Matsudaira Morisada, who is the present head of the Aizu-Matsudaira.[23]
