However, according to "Tanshu sanke monogatari" (the tale of the three families in Tanshu), Yoshisada is said to have been killed in September; and the Buddhist mortuary tablet of 'Mitsunobu ISSHIKI' which exists at the Seirin-ji Temple in Kami-Miyazu also says the date of Yoshisada's death was September 8.
しかし、『丹州三家物語』においては9月に殺害されたとしており、上宮津盛林寺に存在する「一色満信」の位牌においても9月8日と記されている。
