Incidentally, Moritoki ISE (a.k.a. Soun HOJO) was a family lord of the Ise clan, a clan related to Sadachika, in Bicchu Province, and was the son of Morisada ISE (one theory argues that Morisada's wife was Sadachika's sister and the relationship between Sadachika and Moritoki was that of uncle and nephew), who was involved in the shogunate government along with Sadachika and served Yoshimi ASHIKAGA on Sadachika's recommendation.
ちなみに北条早雲（いわゆる北条早雲）は、貞親の同族備中国伊勢氏の当主で貞親と共に幕政に関与した伊勢盛定の嫡男（一説には盛定の妻は貞親の姉妹であり、貞親と盛時は伯父と甥の関係であるもいう）とされ、貞親の推挙によって足利義視に仕えたと言われている。
