Lady Yi of the Jeonju Yi clan or posthumously called as Princess Jeonghwa, was the fifth child, second and youngest daughter of Yi Cha-ch'un and also a full younger sister of Yi Sŏng-gye, the founder of the Joseon Dynasty.

In 1392, her brother made a new dynasty, their father was granted royal title as King Hwan (환왕; 桓王; later Hwanjo; 환조; 桓祖) and their mother was granted the title as Queen Ui (의비, 懿妃; later Queen Uihye; 의혜왕후; 懿惠王后). Under Emperor Gojong of Korea's command, she was then posthumously honoured as Princess Jeonghwa (정화공주; 貞和公主) in 1872. She married Cho In-byŏk, son of Cho Ton from Hanyang Cho clan (한양 조씨; 漢陽 趙氏). After the Joseon Dynasty was established, Cho was then honoured as Internal Prince Yongwon (용원부원군).
