Along with Burleson's Company in January 1860, Gov. Houston had authorized two other Ranger companies to patrol and protect different parts of the Texas frontier from Indians... those were headed by Capts. Conner and Dalrymple.
On the roster for Capt. Conner's company is Andrew J. Clark, age 26, who enlisted in Austin on 20 January 1860.
