The earliest European settlers of Gaston County were principally Scots Irish, Pennsylvania Dutch, and English. In the 1750s, Dutch settler James Kuykendall and others constructed the Fort at the Point at the junction of the Catawba and South Fork Rivers. The fort was built because of ongoing hostilities with the Cherokee, but it was apparently never attacked. Tensions between the settlers and the Native American inhabitants (primarily of the Catawba tribe) were eased considerably when the boundary dispute between North Carolina and South Carolina was settled in 1772, after which most of the Catawba settled on a reservation near Fort Mill, South Carolina.
Most early farms were small, cultivated primarily by White yeoman farmers of English ancestry. North Carolina's colonial policy restricted the size of land grants, and in Gaston County they tended to be about each. One of the earliest grants in the area was given to Captain Samuel Cobrin, commander of a local militia company, on September 29, 1750.
Gaston County was founded in 1846. It is named for William Gaston, member of the state supreme court.
Between 1845 and 1848, Gaston County experienced an industrial boom. During this three-year period, the first three cotton mills in the County were established. Some authorities say that the first one was established by Thomas R. Tate on Mountain Island, near the present site of Duke Energy's Mountain Island Dam and Hydroelectric Station. Other sources say that the first mill was established by the Linebergers and others on the South Fork River near McAdenville. Most sources agree that among the first three mills in operation in the County was the Stowesville Mill, founded by Jasper Stowe and Associates in the South Point Community south of Belmont. Gaston County still leads all other counties in the country both in the number of spindles in operation and in the number of bales of cotton consumed.
