Shō Ietsugu
Shō Ietsugu, known as Saburō, was an early-Kamakura warrior of the Kodama band in Musashi, the third son of Shō Ienaga. After his elder brother Yoriie, the sixth head, fell at the Battle of Ichinotani in 1184, Ietsugu was made Yoriie's adopted heir and became the seventh head.
He later went west to take up the Kusanagi jitō post in Bitchū, settled there, and became ancestor of the Bitchū Shō. The Azuma Kagami mentions him once, in 1250, serving in Kyoto.
