Yi Yang-gil (李陽吉) is venerated as founder of the Chungwon-gong (Yeongnam) branch of the Cheongan Yi clan; his posthumous name is Chungwon. According to the Chungcheong Ilbo surname series he passed the civil examination in late Goryeo, served as Gyeomgyo Sirang and Yebinsa Dongjeong under King Gongmin, was sent to Jeju as magistrate for frank remonstrance, died a martyr in the fifth year of Gongmin (1356) and was later named Lord of Cheongan. Namu Wiki also says he died in the Jeju revolt of 1356.
The Yangsan culture encyclopedia's Cheongan Yi entry dates the same event to 1361 (said to be Gongmin 5), calling it the revolt of Gaeul Jeokhol Gotak and saying he was named a first-class merit subject; the year thus differs (Gongmin 5 corresponds to 1356). Which is right, and the nature of the revolt, could not be verified here from historical records.
The Yeongnam line's mid-founder is said to have come from this line, with clan villages in Gyeongju, Pohang, Uiseong and Ulju. Yi Eung-chun and Yi Bang-rin, who raised militias in the Imjin War, are presented as descendants of this Yeongnam area, but the generations between them and Yi Yang-gil were not confirmed in public sources.
He was sent to Jeju after frank remonstrance, and Namu Wiki says he died while suppressing the Jeju revolt.
The year of his death is 1356 in Chungcheong Ilbo and Namu Wiki, 1361 in the Yangsan encyclopedia.
Yi Eung-chun and Yi Bang-rin are presented as Yeongnam descendants; the Honam branch's founder is Yi Han-beon.
