The town was originally named Milltown due to its number of mills along the East Branch Brandywine Creek, the first of which was founded by Daniel Butter. The Butter family also had paper mills in the area, and Frederick Bicking from Winterburg, Germany, was the patriarch of the Bicking paper families. Around the time of the American Revolution, Milltown became more commonly known as Downingtown after the prominent businessman Thomas Downing, a Quaker immigrant in 1717 from Bradninch, Devon, England, who owned a number of those mills. The town was officially named Downingtown in 1812.
