“In 1851, a small community was formed on the banks of Brushy Creek, near a large round and anvil-shaped rock located in the middle of the creek. This round rock marked a convenient low-water crossing for wagons, horses, and cattle. The first postmaster called the community “Brushy,” and the creek was called “Brushy Creek”. But in 1854, at the suggestion of the postmaster, the small settlement was renamed Round Rock in honor of this now famous rock.”
