The Hyeongpan-gong branch is said to be the senior (eldest-son) line of the Hamyang O clan. According to the genealogy, fourteenth-generation O Yeong-bal (吳穎發) of this branch lived at Gwandong below Mount Cheollyeong in Hamyang, where his tomb also lies, and his descendants lived around Gwandong until the nineteenth generation.
The Duam-gong branch takes its name from the pen name of the late-Goryeo scholar O Sang-deok (吳尙德), Duam. He associated with Yi Saek, Jeong Mong-ju and Yi Sung-in, and is said to have chosen the name Duam to signify cutting ties with worldly honor and disgrace.
His son O Chi-haeng (吳致行) served as magistrate of Jangsu and section chief in the Ministry of Personnel, but withdrew to Mount Hwajang in Hamyang when King Danjong was deposed and became known as the Recluse of Hwasan. The 1909 genealogy was compiled with only the Duam-gong, Jungnangjang-gong and Sain-gong branches taking part.
The name of the Deokgye-gong branch appears to come from the pen name of the mid-Joseon scholar O Geon (吳健, 1521-1574), Deokgye. A disciple of Jo Sik, he passed the civil examination in 1558, served as a section chief in the Ministry of Personnel, took part in compiling the Annals of King Myeongjong, and is enshrined at Seogye Seowon in Sancheong.
His son O Jang (吳長) also passed the civil examination and served as a censor.
The Munwoldang-gong branch takes its name from the pen name of O Geuk-seong (吳克成, 1559-1616), a military official of the Imjin War, and is divided into the Yonggye, Ujae and Chwisudang lines; Chwisudang was the pen name of his son O Yeon (吳演).
O Geuk-seong passed the military examination in 1594 and, as a royal messenger, travelled between the camps of Kwon Yul and Yi Sun-sin reporting on the war; he later served as magistrate of Hwangan and as an officer of the Military Training Office.
