text: Family Gongsun Yue (), Gongsun Zan's younger second cousin. Gongsun Zan sent him with 1,000 troops and supplies to assist the warlord Yuan Shu, who was in a proxy war with his half-brother Yuan Shao. Gongsun Yue died after being hit by a stray arrow during the Battle of Yangcheng in 191 while fighting alongside Sun Jian (Yuan Shu's proxy) against Zhou Yu (Renming) (Yuan Shao's proxy). Gongsun Zan used Gongsun Yue's death as an excuse to declare war on Yuan Shao.
  In the 14th-century historical novel Romance of the Three Kingdoms, Gongsun Yue is Gongsun Zan's younger brother. Gongsun Zan sends Gongsun Yue as a messenger to demand that Yuan Shao keep his promise by dividing Ji Province between him and Gongsun Zan after seizing it from Han Fu, but Yuan Shao refuses. While Gongsun Yue is on his return journey, Yuan Shao orders his men to pretend to be Dong Zhuo's soldiers and then ambush and kill Gongsun Yue. Gongsun Zan sees through Yuan Shao's ruse and subsequently declares war on him.
  Gongsun Fan (), Gongsun Zan's younger second cousin. He leads troops from Bohai Commandery () to join Gongsun Zan. He also fought in the Battle of Jieqiao alongside Gongsun Zan against Yuan Shao.
  Gongsun Xu (), Gongsun Zan's son. During the Battle of Yijing (198–199), Gongsun Zan sent him to seek reinforcements from the Heishan bandits led by Zhang Yan.

Gongsun Xu later met his end at the hands of the Tuge (), a Xiongnu tribe.
