John B. Jones (December 22, 1834 – July 19, 1881) was a Confederate army officer and Texas Ranger captain. Born in Fairfield, South Carolina, his family moved to the Republic of Texas in 1838. In 1874, and after a short incursion in politics, he accepted the offer of commanding a newly formed branch of the Texas Rangers, named the “Frontier Battalion.” This force had the special task of stopping the numerous Indian raids and enforcing the law within the territory of the State.

The Life of Everett Ewing Townsend by Lewis H. Saxton and Clifford B. Casey (1958). "Although some attention has been given to the service of Everett Ewing Townsend as a Texas Ranger, comparatively little is known of the contributions which he made to his State as a mounted customs inspector, sheriff and promoter of law and order, as a state legislator, and in the acquisition and development of the Big Bend National Park."

The 1946 Texarkana Moonlight Murders...Company B of the Texas Rangers arrived in Texarkana, led by the colorful and well known, Captain M.T. "Lone Wolf" Gonzaullas. The Texas Rangers had a reputation of not stopping an investigation until the criminal was caught. Gonzaullas questioned the members of the Rythmaires. His presence in Texarkana added to the newspaper coverage of the case, though it appears that cooperation between the various law enforcement agenices was not good.
