At the end of the Edo bakufu, the 13th lord of the Choshu clan, Yoshichika (the 67th) and the 14th lord Sadahiro (the 68th) were forbidden to keep "慶" and"定" in their names, due to being guilty of Kimmon no Hen (the Kinmon Incident), and their names were changed back to the original "敬親" (Takachika) and "広封" (Hiroatsu) (Hiroatsu changed his name to "元徳," Motonori, after the Meiji Restoration.)
幕末には、13代長州藩主慶親（67代）・14代藩主定広（68代）が、禁門の変の処分として、それぞれ慶・定の名乗りを禁じられたことにより、敬親・広封と初名に名乗りを戻すこととなった（広封は明治維新後に元徳と名乗った）。
