Princess Heungsu
Princess Heungsu (Hangul: 흥수궁주 or 흥수공주, Hanja: 興壽宮主 or 興壽公主; d. 1123) was a Goryeo Royal Princess as the second daughter of King Sukjong and Queen Myeongui who later married her uncle's son–Wang Jeong the Count Seunghwa (승화백 왕정), and received "2,000 sik-eup" (식읍 2,000호) and "300 sik-sil" (식실 300호). She firstly received her title and honor as a princess in 1102 (7th years reign of her father) and in 1105 (her eldest brother's ascension), she was given the "Sungdeok Palace" (숭덕궁, 崇德宮) as her own mansion. Six years later in 1111, Heungsu gave birth to her first son and upon hearing this, her eldest brother sent Gim Go (김고) on board to gave many gifts to her. According to the left records, she bore Wang Jeong two sons: Wang Jae (왕재) and Wang Gi (왕기).
