George Washington Cluck and his wife Harriet "Hattie" were also primary colonizers of Cedar Park. The Clucks arrived in Running Brushy in 1873, purchasing 329 acres situated at the head waters of Brushy Creek. The Cluck home was located on what would become the northwest corner of US 183 and Buttercup Creek Boulevard. The settlement had a post office, and in 1874, Hattie Cluck became the community's first postmistress.
