Archeological evidence suggests that humans dwelled in the area known as Kerrville as early as 10,000 years ago. The early modern residents were successful shinglemakers whose mercantile business became a hub that served the middle and upper Hill Country area in the late 1840s. One of the earliest shinglemakers was Joshua D. Brown. With his family, Joshua Brown had led several other families on an exploration of the Guadalupe Valley. These early pioneers organized their settlements near a bluff just north of the Guadalupe River in the eastern half of today's county. The settlement was referred to as "Brownsborough", but after the area was formally platted in 1856 by James Kerr, a major in the Texas Revolution, the settlement was formally known as "Kerrville" and maintained a county seat with Texas.
