Quick Answer
Dugu Xin was not famous only because of his daughters. He was himself a major Western Wei general and a core member of the Guanlong aristocratic-military network.
His family later mattered enormously. One daughter became empress in Northern Zhou, another became the mother of Li Yuan, and Dugu Jialuo became empress of Yang Jian.
Early Life
Dugu Xin was originally named Dugu Ruyuan. He came from a northern Xianbei military aristocratic background.
The late Northern Wei world was full of garrison unrest, rebellion, and warlord conflict. Like many future Western Wei and Northern Zhou elites, Dugu Xin rose by choosing sides in this unstable military environment.
Rise to Power
Dugu Xin became closely connected with Yuwen Tai. When Emperor Xiaowu moved west to Guanzhong, Dugu Xin followed, entering the core of what became Western Wei.
Western Wei fought Eastern Wei for decades. Dugu Xin served in campaigns, suffered reverses, returned to Guanzhong, and rose to the highest military aristocratic level. His place among the pillar generals made him one of the leading figures of the Guanlong group.
