Gu Yong
Gu Yong's third and youngest son, Gu Ji, inherited his father's peerage as the Marquis of Liling () because his eldest brother died early and his second brother was not in a good state of health to succeed their father. Gu Ji did not have any children so when he died, there was no one to inherit his peerage. During the Yong'an era (258–264), the third Eastern Wu emperor Sun Xiu issued an imperial edict as follows: "The late Imperial Chancellor (Gu) Yong was virtuous and loyal. He played a supportive role to the State with his graciousness. I am deeply saddened to hear that he has no descendant to succeed him. I hereby order (Gu) Yong's second son, (Gu) Yu, to inherit the peerage of the Marquis of Liling, so as to honour (Gu Yong) for his past contributions."
