A.P. and D.E. Rhyne and Ambrose Costner originally owned the Mount Holly Cotton Mill. It was the fourth mill to be built in Gaston County and is the oldest surviving mill today. The mill's success and the prosperity of the area as a whole led local residents to petition the North Carolina General Assembly for incorporation of Mount Holly in 1879.
