According to a "Chu-yu-ki" entry on July 12, 1120, 'the wife of Hoki no kami (Lord of Hoki), Tadamori, died suddenly. She was around Sen-in,' and this shows that the wife of Tadamori was serving Sen-in (Cloistered Emperor Shirakawa).
『中右記』保安元年（1120年）7月12日条には「伯耆守忠盛妻俄に卒去すと云々。是仙院の辺なり」という記事があり、忠盛の妻が仙院（白河法皇）の周辺に仕えた女房だったことがわかる。
