The Motonaga House of the Princely Shō-clan
Written by Motobu Naoki, translated by Andreas Quast
The Motonaga House of the Princely Shō clan belonged to the Shuri Shizoku. The ancestor of the Motonaga House was Motonaga Chōgi (1784–1829), who was a 5th son of the Motobu Udun. Since his wife Manabi was from the Kyan House, the Motonaga House is deeply related to the history of karate.
The father of Kyan Chōtoku was Chōfu. Chōfu was originally a member of the Motonaga House, but also inherited the blood of the Kyan House. Since there were no male heirs in the Kyan House, Chōfu was adopted and inherited the Kyan House.
And, Kyan Chōtoku sensei was also adopted back into the Motonaga House, which he inherited. Thus, Kyan sensei’s real name was, in fact, Motonaga Chōtoku.

Well, the head of the Motonaga House now lives in Osaka. The family grave is also situated in Osaka. The picture below I received from the descendants of the Motonaga House.

Kyan sensei’s first karate master was his own father. Therefore, I think that Kyan sensei learned some of his kata from his father. For example, I wonder if Seisan came from his father Chōfu? In addition, I also think that Kyan sensei adopted Seisan as a basic form was also from the influence of his father.
Below are the genealogies of the Motonaga House, the Kyan House, and the Motobu Udun.
