She was also the biological mother of King Cheoljong of Joseon[1][2] and received her title after her son's ascension to the throne.
[citation needed] Lady Yŏm was a concubine of Yi Gwang (the future Grand Internal Prince Jeongye).
Her life and relationship with Yi Gwang's first wife, Grand Internal Princess Consort Wanyang, is unknown, but from King Cheoljong's Annals of the Joseon Dynasty,[4] we know that he made no difference in serving them when he was a child.
Her tomb was first located in Hongeun-dong, Hanseong-bu,[5] but in 1851 it was moved to Gyeongjwa, Dapdong-ri, Sudong-myeon, Yangju-gun, Gyeonggi Province, South Korea alongside her husband, Grand Internal Prince Jeongye, and his first wife, Grand Internal Princess Consort Wanyang.
The tomb was built by Kim Jwa-geun, younger brother of Queen Sunwon, and the epitaph was written by Yi Ha-eung, Grand Internal Prince Heungseon, who was the father of Emperor Gojong.
