↑Ackroyd، p. 298; n.b. ، Shogun Yoshimasa was succeeded by Shogun Yoshihisa (Yoshimasa's natural son)، then by Shogun Yoshitane (Yoshimasa's first adopted son)، and then by Shogun Yoshizumi (Yoshimasa's second adopted son)
↑Ackroyd، p. 385 n104; excerpt، "Some apparent contradictions exist in various versions of the pedigree owing to adoptions and name-changes. Yoshitsuna (sometimes also read Yoshikore) changed his name and was adopted by Yoshitane. Some pedigrees show Yoshitsuna as Yoshizumi's son، and Yoshifuyu as Yoshizumi's son."
