Sullivan County, North Carolina Genealogy

See Sullivan County, Tennessee for further information about Sullivan County, North Carolina.

From 1784 to 1788 Sullivan County was claimed by the abortive, short-lived State of Franklin.

In 1789 North Carolina ratified the Constitution, was admitted the union, and ceded her westernmost counties to the United States. The United States used these counties to create the Southwest Territory. This territory became the State of Tennessee in 1796.

Sullivan County was part of these western counties now in Tennessee.
