The first European settlers were Welsh. The name Whiteland came from Whitford Garden in Flintshire, Wales. Whiteland Township was divided into two townships in 1765.Native Americans called the area "The Dark Valley" because of the numerous trees and undergrowth. During the American Revolution, Gen. George Washington and many of his troops camped at Malin Hall here. They were preparing for a September 16, 1777, encounter with British General William Howe. The Continental Army also camped near White Horse Inn on Swedesford Road.
