Grand Lady Heonmok

Grand Lady Heonmok of the Gyeongju Pyeong clan was the daughter of Pyeong-Jun. She became the 7th wife of Taejo of Goryeo and mother of Prince Sumyeong.
Among all of Taejo's wives and consorts, she held the highest title below the queen. This indicated that her father made an important contribution - to established the new Goryeo Dynasty and possibly that he was a behind-the-scenes figure who promoted Silla's noble wealth. Through her son, Heonmok became the great-grandmother of Queen Seonjeong.
