TWIN BRANCH. Twin Branch rises four miles southwest of Oakwood in northeastern Leon County (at 31°32' N, 95°55' W) and runs southeast two miles to its mouth on Upper Keechi Creek (at 31°32' N, 95°53' W). It crosses sloping to gently sloping terrain surfaced by sandy loam that supports dense pecan-elm, water oak-elm, elm-hackberry, and post oak-black hickory woods on the banks. Anglo-American settlement in the vicinity began during the latter half of the nineteenth century. The creek appears to derive its name from two small forks that converge near the headwaters.
