His personal name was Yi Gwang (이광; 李㼅), but he was also known as Kwae-deuk (쾌득; 快得) or Hae-dong (해동; 海東).
In 1801, Prince Euneon was executed after his legitimate wife, Princess Consort Sangsan of the Jincheon Song clan and his daughter-in-law, Princess Consort Shin of the Pyeongsan Shin clan (the wife of Prince Sanggye), had been baptized into the Roman Catholic Church.
Some of Prince Euneon's sons, including Yi Gwang, were exiled on Ganghwa Island where they lived as poor farmers, but in 1822 the family received a special pardon from King Sunjo.
In 1849, his son, Yi Won-beom, born to a concubine named Lady Yeom, became the new monarch of Joseon as King Cheoljong.
His tomb was originally in Jingwan, Eunpyeong District, Seoul, northwest of his father, Prince Euneon's grave, but it was moved to Yeoju, and in August 1851, to Seondan-ri, Pocheon-eup, near Wangbang Mountain.
