Date Munemura
Date Munemura (1173–1251) was the second head of the Date clan of Mutsu, the second son of Date Tomomune by a daughter of the Yūki house. The Azuma Kagami lists him as Tameshige among the four sons who fought beside their father in the 1189 Ōshū campaign, after which the family received Date district.
Old Date genealogies even name Munemura, rather than Tomomune, as the clan's founder. He was the father of Date Yoshihiro.
