He died at the age of 50 in 1785, and is buried in the Sugaw Creek Presbyterian Church Cemetery, Charlotte, Mecklenburg County, North Carolina. His will was probated August 20, 1786. In 1796, heirs of Nicholas Flynn were awarded a Tennessee, North Carolina Revolutionary War Land Warrant in what would become Tennessee.
Family history tells that Nicholas Flynn came to the colonies as an indentured servant, was sold to a cabinet maker who taught him reading, writing and arithmetic, which enabled his descendants to be educated, becoming preachers and teachers. This occupational tradition is still in his descendants.
