Thornton Gap was named for Francis Thornton (1711–April 14, 1749), owner of the land to the east and the "F.T. Valley". In 1740, he built a mansion in the Piedmont region near
Nethers in
Rappahannock County. Historian J. Houston Harrison indicates in 1737 the Harrison family migrated through the Gap from Alexandria before their settlement in the valley and founding of Harrisonburg. The privately owned Thornton's Gap Turnpike Company was formed to build a road over the mountains at Thornton's Gap. The
toll road opened in 1806. Thornton Gap was one of the passages through the Blue Ridge Mountains between the Shenandoah Valley and the Piedmont region of Virginia used by
Confederate General
Stonewall Jackson to move his famous "
foot cavalry" troops during the
American Civil War. Prior to the building of the
Shenandoah National Park and the
Skyline Drive by the federal
Works Progress Administration (WPA) during the
Great Depression, the town of Beahm was located at Thornton Gap. Sculptor
William Randolph Barbee was the son of a toll collector at Thornton Gap; his son
Herbert later erected a bust in his memory at the site. ==Current information==
