The above is the conventionally accepted theory, but there is another theory which holds that the descendant of Ujitsuna ROKKAKU (the heir of Takayori and elder brother of Sadayori) survived under the aegis of Nobunaga, and that Yoshisato ROKKAKU (the old vassal of Yoshihide ROKKAKU, who was the father or elder brother, and the Kataimina (a name for a dead person)) served Hideyoshi TOYOTOMI to become a feudal lord of 120,000 koku, was given the Toyotomi cognomen and the title of palace staff and was consistently well treated, all of which has been the prevailing theory in modern times.
以上が従来の通説であるが、異説としては、六角氏綱（高頼の嫡男で定頼の兄）の子孫が信長に庇護され存続し、六角義郷が、（父あるいは兄にあたる六角義秀の旧臣であり、片諱を与えた）豊臣秀吉に仕えて12万石の大名となり、豊臣姓と侍従の称号を授かり始終優遇されたとされ、近年有力視されている。
