Note that her first name was mentioned in "Mido Kanpakuki" (FUJIWARA no Michinaga's diary) written by her father Michinaga or in "Shoyuki" (Diary of FUJIWARA no Sanesuke) written by FUJIWARA no Sanesuke, and it is believed that she changed her name when she married since her first name was the same as the name of MINAMOTO no Takahime (Imperial Prince Tomohira's daughter) who was the older sister of her husband and also the legal wife of FUJIWARA no Yorimichi who was her older brother born to a different mother.
なお、初名については父・道長の『御堂関白記』や藤原実資の『小右記』に記されており、婚姻時に夫の姉で尊子の異母兄藤原頼通の正室でもあった源隆姫（具平親王皇女）の名前と重なるために改名したと考えられている。
