Lady Sinjuwon of the Sincheon Gang clan[1] (Korean: 신주원부인 강씨; Hanja: 信州院夫人 康氏; lit.
Lady of the Sinju Courtyard) was the daughter of Gang Gi-ju who became the 23rd wife of Taejo of Goryeo.
Gang was also the uncle of Queen Jeonghwa; who was the great-grandmother of Wang Geon, King Taejo, her husband.
There is a speculation that Gang, who was from Hwangju, may have helped her in marrying Wang So as Gang's and Daemok's clan both came from the Hwangju region.
