In 1408 at the age of 13, she was arranged to marry King Taejong's son, Prince Chungyeong, to which her title became Princess Gyeongsuk (경숙옹주; 敬淑翁主).

It's said that she was chosen for the marriage due to the fact that King Taejong's older sister, Princess Gyeongseon, was her paternal aunt; thus having royal family connections.

On 6 July 1418, during the 18th year of Taejong's reign, Princess Gyeongsuk became Crown Princess Gyeong (경빈; 敬嬪) when Grand Prince Chungyeong (later King Sejong) became the crown prince successor to the throne, and when her husband became king on 9 September 1418, her title changed to Queen Gong (공비, 恭妃; Gongbi meaning Courteous Consort).

It's said that Queen Gong had a gentle and kind appearance but advocated strict adherence to laws and code of conduct.

Queen Soheon was buried with her husband, King Sejong in a burial mound, surrounded by statues of scholars, military officials, and horses.

Prince Suyang commissioned the creation of the Seokbosangjeol after the death of his mother, Queen Soheon, intending it to ease her passage to the next life.

It was translated from Chinese to Korea's native hangul characters, and as such represents the oldest form of indigenous Korean written text.
