Early Hamilton County boundaries before 1803
Hamilton County underwent multiple boundary changes before Ohio became a state in 1803. In 1792, Hamilton County, Northwest Territory, covered most of the western third of the current state of Ohio and part of Michigan to the Canadian border. From 1798 to 1803, several counties in southeastern Indiana were also part of Hamilton County. Read Early Hamilton County Boundaries, compiled by John Tholking, for further details and maps.
