His daughter, who was called Wakagozen (reportedly the name 'Wakagozen' was derived from the fact that, in order to hear her koto play, the Cloistered Emperor Toba made her enter the imperial court wearing a male costume), had a gift that was even better than Munesuke's and, reportedly, FUJIWARA no Moronaga (FUJIWARA no Yorinaga's son, later Daijodaijin), who was called the greatest musician of the day leaned koto play from Munesuke and his daughter.
また、娘・若御前も父に勝るとも劣らない才能を持ち（「若御前」とは、鳥羽法皇が彼女の曲を聞くために男装をさせて院の御所に上げさせた事に由来していると言う）、後に当代随一の音楽家として名を残した藤原師長（藤原頼長の子、後の太政大臣）の筝もこの親子から習ったものであると伝えられている。
