浜松藩
Matsudaira Norinaga was the eldest son of Matsudaira Ienori, a Sengoku period samurai and daimyō of Iwamura Domain in Mino Province under the early Tokugawa shogunate. On the death of his father in 1614, he was confirmed as head of the Ogyū-Matsdaira clan and the same year accompanied the forces of "Shōgun" Tokugawa Hidetada at the Siege of Osaka. In 1634, he was transferred to Hamamatsu Domain in Tōtōmi Province with an increase in revenues from 20,000 to 36,000 "koku".
