Murong De
During Former Yan, Lady Duan, was the wife and probably princess of Murong Na (慕容納) the Prince of Beihai. After Former Yan's destruction by Former Qin in 370, the Former Qin emperor Fu Jiān initially made Murong Na a commandery governor, but later Murong Na was relieved from that post and relocated, along with his mother Lady Gongsun and Lady Duan to be with his younger brother Murong De, who was the governor of Zhangye Commandery (張掖, roughly modern Zhangye, Gansu). (Murong Na and Murong De had the same mother.) Later, when Murong Na's brothers Murong De and Murong Chui rebelled against Former Qin in 384, with Murong Chui establishing Later Yan and becoming its emperor, Fu Chang (苻昌) the new governor of Zhangye arrested and executed Murong Na and all sons of Murong De and Murong Na. At that time, Lady Duan was not executed because she was pregnant, but she was imprisoned to await execution after she gave birth.
