O Baek-ryeong was a mid-Joseon official from Dongbok, pen name Mukjae, son of O Se-hyeon and younger brother of O Eok-ryeong; his wife is recorded as a daughter of Go Gyeong-ryong. His dates were not confirmed here.
He passed the civil examination under Seonjo, was enfeoffed as Lord Bokcheon as a deputy royal secretary under Gwanghaegun, and under Injo served as chief royal secretary and Inspector-General, then Vice-Minister of Personnel and grand master of the academy.
His descendants form the core of the family: his eldest son O Jun became a senior minister and master calligrapher, and O Dan became Governor of Hwanghae and father-in-law of Grand Prince Inpyeong. This line is called the Mukjae-gong branch. One source makes O Jun O Dan's father, which conflicts with their birth years, so Wikipedia's version is followed here.
O Baek-ryeong entered office under Seonjo and served through the reigns of Gwanghaegun and Injo. Being enfeoffed as a lord under Gwanghaegun is notable, since such titles often reflected merit or royal ties, but for what service he received it could not be confirmed here. His senior posts under Injo suggest he kept trust after the Restoration, and both sons reaching high office shows the family's base was laid by him.
Through his sons O Jun and O Dan the line is said to continue to O Jeong-il and O Jeong-wi.
