가후
Jia Xu had at least three sons. His eldest son, Jia Mu (賈穆), was a Chief Commandant of Escorting Cavalry (駙馬都尉). After Jia Xu's death, Jia Mu inherited his father's marquis title, Marquis of Weishou District (魏壽鄉侯). He also served as the Administrator (太守) of various commanderies. Jia Xu's youngest son, Jia Fang (賈訪), was given a marquis title and 200 taxable households around the same time as when Jia Xu was enfeoffed as the Marquis of Weishou District. According to the "Xin Tang Shu", Jia Xu had a son, Jia Ji (賈璣), who also served as a Chief Commandant of Escorting Cavalry like Jia Mu, and held the title of a Secondary Marquis (關內侯). Jia Ji is not mentioned in Jia Xu's official biography in the "Sanguozhi".
