Tennessee County, Tennessee Genealogy

United States Tennessee  Tennessee County

Tennessee County was organized in 1788 on land in the modern state of Tennessee, but which at the time was part of North Carolina. It was formed from part of the old Davidson County. In 1789 when North Carolina ratified the new Constitution and entered the union, North Carolina ceded its western area, now Tennessee, to the federal government.

In 1796 the modern state of Tennessee was admitted to the union. That was when Tennessee County gave up its name for use by the new state. Tennessee County was then divided into Montgomery and Robertson counties. The land of the extinct Tennessee County now forms the modern Humphreys, Montgomery, and Robertson counties and portions of Stewart, Dickson, Cheatham, and Houston counties.

The records of extinct Tennessee County are now found in Robertson County, Tennessee.
