During the reign of King Shinjong of Goryeo, her grandfather, Kim Bong-mo (김봉모, 金鳳毛; ?–1209), served as Pyeongjangsa (평장사; 平章事) and received the posthumous title of Jeongpyeong (정평; 靖平).
Through her great-great-grandmother, Lady Kim was a fourth cousin twice removed of Queen Wongyeong as they shared Min Yeong-mo as their ancestor, and would eventually become her sister-in-law through marriage.
Her father was given the royal title of "Internal Prince Wolseong, Kim Cheon-seo" (월성부원군 김천서; 月城府院君 金天瑞), and her mother was given the royal title of "Internal Princess Consort Samhanguk of the Damyang Lee clan" (삼한국대부인 담양 이씨; 三韓國大夫人 潭陽 李氏).
In the aftermath of the Second Strife of Princes when her husband abdicated in favor of his younger brother, Yi Bang-won, Prince Jeongan on 28 November 1400, along with him being bestowed the courtesy title of "King Emeritus Inmungongye" (인문공예상왕), she was bestowed the courtesy title of "Queen Dowager Sundeok" (순덕왕대비, Sundeok-Wangdaebi) by her royal brother-in-law.
In 1681, 270 years after her death, King Sukjong added Onmyeongjangui (온명장의; 溫明莊懿) to her posthumous title.
