《汉书·传·公孙刘田王杨蔡陈郑传》
他的儿子杨忠继承爵位，因为杨敞位居丞相参预制定废昌邑王更立宣帝的大策，安定漠室宗庙有功，增加食邑三千五百户。
子忠嗣，以敞居位定策安宗庙，益封三千五百户。
His son Yang Zhong inherited his title. Because Yang Chang had served as Prime Minister and participated in the grand plan to depose King Changyi and reinstate Emperor Xuan, stabilizing the Mo Shizong Temple and rendering meritorious service, his fief was increased by 3,500 households.
