Biography Early life The future Grand Internal Princess Consort Hadong was born into the Hadong Jeong clan on 23 September 1522 as the daughter of Jeong Se-Ho, and his wife, Lady Yi of the Gwangju Yi clan.

Her father, Jeong Se-Ho was the son of Jeong Sang-Jo and Lady Ahn of the Juksan Ahn clan; making him the grandson and Lady Jeong a great-granddaughter of Chŏng Inji. Her paternal grandmother, Lady Ahn, was the granddaughter of Princess Jeongui; who was the second daughter of Queen Soheon and King Sejong. Thus making her a great-great-granddaughter through her grandmother.

Meanwhile, her mother was the daughter of Yi Se-geol and Lady Jeon of the Jeongseon Jeon clan. Lady Jeong had 2 older brothers and a younger brother. Her paternal cousin, Lady Jeong of the Hadong Jeong clan, eventually became the grandmother of Queen Yu, the wife of King Gwanghaegun who was also the princess consort’s grandson.

Marriage and later life She later married Yi Cho when he was still Prince Deokheung and was honoured as Princess Consort Hadong with the rank of Junior 1 (종1품). Her father was then honored as Duke Hyogan, Internal Prince Hadong .

During her marriage, she gave birth to a son in 1545, a second son in 1546, a daughter in 1548, and a third son in 1552.

On 24 June 1567, during King Myeongjong's 22nd year of reign, she died at 46 years old. Her tomb is located near from her husband's tomb.

Seonjo's ascension to the throne Two months after her death, her third son, Yi Yeon, Prince Haseong succeeded Myeongjong who died without a royal heir. Thus becoming Myeongjong's adopted son when the prince ascended the throne as the 14th king of Joseon. Her husband couldn't be King because of his low background, so the throne was immediately passed down to his legitimate son.

On 1 November 1569, as the Princess Consort was the biological parent of the reigning King, she was granted the royal title of Princess Consort Hadong at first with the rank of Senior 1 (정1품), but was later changed to Grand Internal Princess Consort Hadong with the same rank.
