Williams died on December 15, 1833, in Charleston, South Carolina en route to St. Augustine, Florida at just 37 years of age, leaving his widow to care for their six young children. His remains were returned to Richmond and interred in the newly established Hollywood cemetery. A nephew of the same name, John Green Williams (1843–1922), became a Confederate soldier and courier for Gen. Jubal Early, and after the American Civil War, Commonwealth's Attorney for Orange County.
