According to "Heiji Monogatari" (The tale of the Heiji), in the Heiji Disturbance, 'Tada kurodo dayu Yorinori (maybe a misunderstanding of Yorimori)' supported the Nobuyori FUJIWARA and Yoshitomo MINAMOTO side to attack Sanjo Palace together, so that he was appointed as governor of Settsu Province as a reward after the war, while it is unclear about the clan at that time as other historical materials do not mention Tada-Genji.
続く平治の乱では、「多田蔵人大夫頼範」（頼盛の誤伝か）なる人物が藤原信頼・源義朝方として三条殿襲撃に加わり、戦後恩賞として摂津守に任官されたことが『平治物語』にみえているが、その他の史料における所見はなく、多田源氏の動向は詳らかではない。
