Emperor He
After Empress Dowager Dou died in 97, officials revealed to Emperor He that Consort Liang was actually his birth mother. While Emperor He rejected a recommendation to posthumously demote Empress Dowager Dou, he reburied his mother and aunt with great honors (but not with his father -- that honor was reserved for Empress Dowager Dou, as his father's wife). He also posthumously rewarded his mother the title of empress.
