Concord Township is first mentioned in court records on June 27, 1683 when John Mendenhall was appointed constable of "Concord liberty". The  paper for the first currency printed by the Continental Congress was made at the Ivy Mills founded by Thomas Willcox and Thomas Brown. The Ivy Mills was the second oldest paper mill in the United States. The mill made printing paper for Benjamin Franklin and paper for currency for several Continental governments, the US government and many South American countries. The oldest Roman Catholic parish in Pennsylvania began as a mission at the home of the Willcox family in 1730. The church was later moved approximately one mile east to the top of the hill into what later would become  the Borough of Chester Heights and is known as St. Thomas the Apostle Church. In 1702, the St. John's Episcopal Church was founded on land donated by John Hannum, a successful farmer and tavern owner who was baptized by the former Quaker George Keith. Keith was known to conduct services at the Hannum home on Concord Road. The Newlin Grist Mill has been grinding grain since 1704. It has an tall stone wheel housed in a timber frame. The mill and processing complex had later passed through various hands, but in the 1950s it was purchased by a direct  descendant of Nicholas Newlin, which along with of surrounding countryside became the Newlin Mill Historic Park. The mill complex area was home to the Markham post office and Markham train station (Philadelphia/Baltimore rail traffic) The name "Concord" was believed to have been given by the earliest European settlers of the township and reflects the harmonious feelings among them at the time. Title to all real estate in the township can be traced back to a grant from William Penn. Concord Township was a part of Chester County until 1789, at which point Delaware County was created by act of  legislature. Farmers in the northern and western reaches of Chester County were weary of travelling a period of days to get to the county seat in Chester, on the Delaware River. The seat of Chester County was moved to Turk's Head, now West Chester, and was centrally located in the county.
