History
Fannettsburg was established in the early nineteenth century as part of the broader settlement of Franklin County, which was itself formed in 1784 from Cumberland County as Pennsylvania's frontier pushed westward. The area's economy historically revolved around farming, timber harvesting, and small-scale milling operations that took advantage of the region's forested ridges and valley waterways. The borough's name is believed to derive from the Fannett Township in which it was originally situated, reflecting the early administrative geography of Franklin County.
