Five Points, Horns Crossroads, Liberty Hill, Milner Crossroads, Patillo, Redbone, Unionville, Weldons Crossroads, and Woodfin Mill are older place names that appear on historical maps of the county but have no current population figures or independent postal designation; several are alternate names for road junctions near the communities listed above rather than distinct settlements. The community of Piedmont was carried in an earlier version of this list but is a regional descriptor for the surrounding physiographic province, not a place name, so it has been dropped here.<\/p>\n
