Although a Lady Ro is mentioned in the genealogy of the Kanmu-Heishi (Taira clan) in the "Sonpi Bunmyaku" (Lineage Sects of Noble and Humble) as the daughter of Kiyomori by Tokiwa, this book was written at the end of the period of the Northern and Southern Courts (Japan) with further information being added from the Muromachi period onwards, and it is possible that this information was a late addition.
『尊卑分脈』の桓武平氏系図で清盛の娘の一人に常盤を母とする廊御方が記されているが、この書物の成立自体が南北朝時代(日本)末期であり、室町時代以降にも多くの加筆が加えられているので、後代の人が物語に見える説を取り入れ書き加えた可能性がある。
