却说公孙渊乃辽东公孙度之孙,公孙康之子也。建安十二年,曹操追袁尚,未到辽东,康斩尚首级献操,操封康为襄平侯;后康死,有二子,长曰晃,次曰渊,皆幼;康弟公孙恭继职。曹丕时封恭为车骑将军、襄平侯。
This Kungsun Yüan was of a family long settled in Liaotung. When Ts‘ao Ts‘ao was pursuing Yüan Shang, who had fled eastward, Kungsun K‘ang, the father of the present rebel, had captured him, beheaded him and sent his head to Ts‘ao. For this service Kungsun received the title of “Marquis of Hsiangpʻing.” After Kungsun K‘ang’s death, as his two sons were young, his brother took the chiefship, and Ts‘ao P‘ei, beside confirming the marquisate, gave him the rank of General. A few years later, the second son, Yüan, being now grown up, well-educated and trained in military exercises, obstinate and fond of fighting, took away his uncle’s power and ruled the heritage of his father. Ts‘ao Jui conferred upon him the title of Yang-lieh , “Wielder of Ferocity,” and made him Prefect.
