Circle Bar Ranch consists of approximately 50,000 acres and located in Foard, Baylor and Knox counties, was established mainly from three historic ranches located in Truscott. The three ranch families were the Craig, Browder, and Shawvers. Jim Craig registered his brand in 1883 and later moved to Truscott in 1885, where the half dugout they occupied for three years still exists. C.I. Browder registered his brand in 1883 and later moved to Truscott in 1896. The one room rock house, which some of their family occupied, is located on that same property today. They later built a house on three sections of land which is located southwest of Truscott and is one of the oldest existing houses in Knox County. John and Bob Shawver homesteaded land east of Truscott in the early 1880's. Jerry Bob was born on this ranch in 1958.

Eugenie's family founded the Pitchfork Ranch near Guthrie, Texas in 1883. Eugenie is the only member of the Williams family who has committed her life full-time to ranching. She manages the horse operation and breeding of Circle Bar Pistol and Circle Bar Mr. Pepto, the ranch stallions. Circle Bar Pistol has accomplishments in AQHA shows in Ranch Versatility, RHAA and ranch rodeos since September 2007.

Circle Bar Ranch is a family operation that employs ten full-time personnel including Jerry Bob and Eugenie's son, Colton, who graduated from Texas Tech University and is currently manager in charge of personnel and market development. The Daniels pride themselves on their loyal employees who make Circle Bar Ranch what it is today.
