Round Rock

Round Rock is on Interstate Highway 35 in south central Williamson County, sixteen miles north of downtown Austin. It was established on the north bank of Brushy Creek where Jacob M. Harrell, formerly a blacksmith in Austin, set up his shop during the spring of 1848. The settlement was first called Brushy Creek. Thomas C. Oatts, who became the first postmaster in 1851, was asked by postal officials to submit another name, and on August 24, 1854, the town officially became Round Rock, as suggested by Oatts and Harrell, who often fished together from a large anvil-shaped limestone rock in Brushy Creek near their dwellings. The Chisholm Trail, used by early cattle drivers on their way to Kansas, passed through Round Rock, crossing Brushy Creek near the rock.
