Liberty Hillbr/Williamson County, Texasbr/ 30 43.840' N 97 54.619' Wbr/br/Text: Samuel Mather settled here in 1849, building a grist mill on the North San Gabriel in 1852. John G. Stewart opened a store near the mill. A small log cabin was in use by 1854 for church, school and lodge meetings. A post office was established in 1858, Mather being postmaster. W. L. Brizendine owned the mill by 1865, adding a cotton gin. Known as Mather's Mill, Brizendine Mill, or Gabriel Mills, the village thrived until Austin amp; Northwestern Railroad bypassed it (1881); then a decline began. The post office closed in 1905, and by the 1920s the town itself had disappeared.
