DUBOSE, TEXAS. Dubose was on the Texas-Mexican Railway fifteen miles southwest of Benavides in southern Duval County. A post office was established there in 1911 with John F. Dubose, after whom the community was named, as postmaster. In 1914 the community had a general store and cotton gin. Estimates of the Dubose population remained at twenty-five from the mid-1920s to the mid-1940s. Its post office was closed in 1929, and the community no longer appeared on maps of the area by the late 1940s.
