Lady Sohwangjuwon () was the daughter of Sun-Haeng《고려사》권88〈열전〉권1 - 소황주원부인 who became the 24th wife of Taejo of Goryeo. Since in her name was added "Little" (), so it seems that her relative became Taejo's wife too and the most suitable was Lady Hwangjuwon. Due to this, it was presumed that Lady Sohwangjuwon also came from the Hwangju Hwangbo clan.
