The Miljik-gong branch descends from Yi Baek-nyeon (李百年), the eldest son of the central ancestor Yi Jang-gyeong (李長庚). He passed the civil examination in 1285 (11th year of King Chungnyeol) and rose to office in the Royal Secretariat (miljiksa).
He is said to have moved to Hamyang with his younger brother Yi Eok-nyeon and spent his last years there. In Seongju the clan's settlements are mostly those of Yi Baek-nyeon's and Yi Jo-nyeon's descendants, and many descendants of Yi Seok-gyeon (李碩堅) of this branch live in Goryeong.
The Chamji-gong branch descends from Yi Cheon-nyeon (李千年), the second son of Yi Jang-gyeong, who served as an assistant executive in political affairs (chamji jeongsa).
All five of Yi Jang-gyeong's sons passed the civil examination and rose to office, which made the Seongju Yi prominent. Yi Cheon-nyeon's second son Yi Seung-gyeong (李承慶) is said to have served at the Yuan court.
The Sijung-gong branch descends from Yi Man-nyeon (李萬年), the third son of Yi Jang-gyeong, who served as chancellor (munha sijung).
Its settlements include Singok-ri in Joma-myeon and Jijwa-ri in Buhang-myeon, Gimcheon, North Gyeongsang Province.
The Yusu-gong branch descends from Yi Eok-nyeon (李億年), the fourth son of Yi Jang-gyeong, who served as governor of Gaeseong (Gaeseong yusu).
He is said to have moved to Hamyang with his elder brother Yi Baek-nyeon, and Hamyang preserves the site of Dojeong Jeongsa, where the two brothers are said to have studied.
The Munyeol-gong branch descends from Yi Jo-nyeon (李兆年, 1269-1343), the fifth son of Yi Jang-gyeong, who served as a senior academician (jeongdang munhak) and received the posthumous title Munyeol. He was an official active from the reign of King Chungnyeol to that of King Chunghye.
His grandsons Yi In-bok (李仁復), son of Yi Po, and Yi In-im (李仁任), who held great power in late Goryeo, came from this branch. Descendants live in Seongju, Goryeong and Gimcheon, among other places.
