Tian Jun
Lady Ma was born in 890, during the reign of Emperor Zhaozong of Tang. Her father Ma Chuo was an officer serving under Qian Liu, a warlord who then controlled the region around Hang Prefecture (杭州, in modern Hangzhou, Zhejiang), who would eventually found Wuyue as King Wusu. (She was said to be from Anguo County (安國), which might have been referring to Qian Liu's hometown Yijin Base (衣錦軍, in modern Hangzhou), as it was also known as Anguo Yijin Base.) Ma Chuo was, either by familial relations or by personal relations, was very close to Qian, as, because of those relations, he married one of Qian's younger sisters. At some point, Qian also took Lady Ma to be the wife of his son Qian Chuanguan. (Qian Chuanguan had been forced to marry the daughter of another late-Tang warlord, Tian Jun the military governor of Ningguo Circuit (寧國, headquartered in modern Xuancheng, Anhui) as a political marriage and was taken to Ningguo, in 902, and was not able to return to Qian Liu's domain until Tian's downfall in 903, so his marriage to Lady Ma would have come after.)
