Princess Seunggyeong

Princess Seunggyeong (died before 1158) or Royal Princess of the Seunggyeong Palace was a Goryeo Royal Princess as the first and eldest daughter of King Injong and Queen Gongye, also the eldest aunt of Gangjong and Huijong.

In 1148, she, as the High Princess  and her younger sister formally became a princess. She later married Duke Gangneung 's son, Wang Yeong the Count Gonghwa and had a daughter and a son together. Their daughter died in 1185 unmarried, while their son married Seunggyeong's niece–Princess Hwasun and died in 1218.

According to her daughter's epitaph (왕영녀왕씨묘지명, 王瑛女王氏墓誌銘), Princess Seunggyeong (Lady Wang's mother) died when Wang unreached the age of 7/8 years. From this point, Seunggyeong was believed to have died before 1158 since Wang was born in 1150.
