On December 29, 1856, Dr. Richard Rodgers Peebles and James W. McDade organized the Hempstead Town Company to sell lots in the newly established community of Hempstead, which was located at the projected terminus of Houston and Texas Central Railway. Peebles named Hempstead after Dr. G. S. B. Hempstead, Peebles's brother-in-law. Peebles and Mary Ann Groce Peebles, his wife, contributed 2,000 acres of the estate of Jared E. Groce, Jr., for the community. On June 29, 1858, the Houston and Texas Central Railway was extended to Hempstead, causing the community to become a distribution center between the Gulf Coast and the interior of Texas. On November 10 of that year, Hempstead incorporated. The Washington County Railroad, which ran from Hempstead to Brenham, enhanced the city upon its completion.
