Foster, John R.

John R. Foster, probably the son of the Old Three Hundred settler, fought with the Texas army during the Siege of Béxar. He appears to have been part of Travis’s cavalry detachment that captured a herd of Mexican horses outside of San Antonio. In mid-November 1835 Travis dispatched the captured herd to Gonzales under the charge of John R. Foster. In 1837 this Foster petitioned for the organization of Fort Bend County.
