Williamson County Was Established in 1848 and Named for a Colorful Judge

Williamson County was formed on March 13, 1848. It was named after Robert M. Williamson — a judge, politician, and soldier who played a notable role in early Texas history. Anglo settlement of the area began during the Texas Revolution, with Kenney's Fort established as early as 1838.

Early settlers were drawn by clear water, fertile soil, and low land prices along the San Gabriel River. The Tonkawa people had a village in the area before Anglo settlement arrived. Georgetown was established as the county seat in the summer of 1848.
