Sobugam Pansa-gong-pa, Taeja Cheomsa-gong-pa, Tongnyemun Busa-gong-pa, Daejanggun-gong-pa, Yebu Sangseo-gong-pa
The Sobugam Pansa-gong branch takes Yi Hyeon-ryeo (李賢呂) as its central ancestor and is also written Pan Sobugamsa-gong-pa. Because the Yeonan Yi genealogy after the founder Yi Mu is lost, each branch counts its own central ancestor as the first generation.
The branch was raised to prominence in early Joseon by Yi Seok-hyeong (李石亨, posthumous title Mungang), and is said to have produced eight state councillors and six chief academicians (daejehak). Members include Yi Jeong-gwi (李廷龜, pen name Wolsa), a great-great-grandson of Yi Seok-hyeong; Yi Gwi (李貴), a fifth-generation descendant and merit subject of the 1623 Injo Restoration, with his sons Yi Si-baek and Yi Si-bang; and Yi Myeong-han, Yi Il-sang and Yi Cheon-bo.
The Taeja Cheomsa-gong branch takes Yi Seup-hong (李襲洪) as its central ancestor and contains seventeen sub-branches.
Members include Yi Gwi-ryeong (李貴齡, Gangho-gong), who took part in the founding of Joseon and became honorary left state councillor, and Yi Gwang-jeong (李光庭), a royal-escort merit subject and upright official. The independence activist Yi Dong-nyeong (李東寧), chairman of the Provisional Assembly of the Korean Provisional Government, was a 25th-generation descendant of Yi Seup-hong. The Ansan Yi clan is said to have split off from Yi In-su, a descendant of Yi Seup-hong.
The Tongnyemun Busa-gong branch takes Yi Ji (李漬) as its central ancestor, and together with the Taeja Cheomsa-gong and Sobugam Pansa-gong branches it forms the core of today's Yeonan Yi.
Members include Yi Suk-gi (posthumous title Jeongyang), who was enfeoffed as Prince of Yeonan and served as minister of taxation; his great-grandson Yi Ho-min (李好閔), enfeoffed as Prince Yeolleung; and Yi Hu-baek (李後白), counted as the clan's first holder of both chief academician posts.
The Daejanggun-gong branch takes Yi Song (李松) as its central ancestor.
The Yeonan Yi are divided into branches starting from about ten central ancestors who held different Goryeo offices, and this branch also counts Yi Song as its first generation.
The Yebu Sangseo-gong branch takes Yi Haek (李核) as its central ancestor.
It is listed as one of the several branches of the Yeonan Yi, alongside the Ibu Sirang-gong, Jeonbeop Panseo-gong, Miljik Busa-gong, Pando Jeongnang-gong and Yeonggwang Gunsa-gong branches.
