Ii Naosuke
Naritsugu also attempted to convince the Shōgun to allow him to trade territories with Hikone Domain under the control of the Ii clan; however, he died in 1835 at the domain’s Edo residence at the age of 25, possibly due to illness, before a decision was reached. This was one of the causes of the ill-will between the "Tairō" Ii Naosuke and future "daimyō" of Fukui, especially Matsudaira Shungaku.
