Zhang Bao had a son, Zhang Zun (張遵), who served as a Master of Writing (尚書) in the Shu government and was killed in battle at Mianzhu in 263 during the Conquest of Shu by Wei. Zhang Bao also had a younger brother, Zhang Shao (張紹), who inherited their father's peerage and served as a Supervisor of the Masters of Writing (尚書僕射) in the Shu government. After the fall of Shu in 263, Zhang Shao was enfeoffed as a marquis by the Wei government along with many other former Shu officials who surrendered.
