Residents disagreed as to whether Augusta or Brownsborough should be the county seat of Richmond County. At the insistence of William Few, the county was partitioned and Columbia County
was created December 10th, 1790 from the northern part of Richmond County. This did not end the controversy about location of the county seat. The citizens of Columbia County turned to arguing among themselves. Supporters built one courthouse in Brownsborough, and those of Cobbham built another. The courthouse at Cobbham was used; and Brownsborough in short order ceased to exist.
