## History

The Franklin Furnace Historic District, Chambersburg and Bedford Turnpike Road Company Toll House, and Woodland are listed on the National Register of Historic Places.
The account of the township's formation was lost when the Confederates burned the county seat Chambersburg in 1864, but according to the recollection of older citizens the township was organized ca. 1818 on territory taken from Peters and Hamilton townships. The area was settled in the 1740s by, among others, Col. John Armstrong, John Campbell, and John Dixon. There were several Campbell families among the early settlers, and an eighteenth-century map labels the village simply "Campbells". It was later called "Campbelltown", a designation that prevailed for many years until, at the suggestion of William Archibald, it received the official designation "St. Thomas", purportedly still honoring Thomas Campbell, who had laid out the village. The name "Saint Thomas" was reportedly a joke concerning Thomas Campbell's tendency to swear. The organization of the town appears to have been concurrent with the organization of the St. Thomas or "Campbeltown" Presbyterian Church in 1818. Not long afterwards local Evangelical Lutheran and German Reformed congregations joined the Presbyterians in the erection of a church building, which the three congregations shared from 1829 until 1854.

## Geography

The township is in west-central Franklin County, in the Great Appalachian Valley, but extending northwest to include the first four ridges of the Ridge and Valley Province of the Appalachian Mountains: from east to west, Front Mountain, Broad Mountain, Little Mountain, and Blue Mountain. Conodoguinet Creek, a tributary of the Susquehanna River, rises in the extreme western corner of the township, at the juncture of Little and Blue mountains. The rest of the township is drained by tributaries of Conococheague Creek, part of the Potomac River watershed.
U.S. Route 30 crosses the township, leading east to Chambersburg, the county seat, and west to McConnellsburg. It passes through the unincorporated community of St. Thomas at the center of the township. The community of Williamson is at the southern corner of the township, where Back Creek joins Conococheague Creek.
According to the United States Census Bureau, the township has a total area of 51.9 square miles (134.3 km$^2$), of which 0.03 square miles (0.08 km$^2$), or 0.06%, is water.
