Warwick Township was formed by the division of East Nantmeal in 1842 and received
its name from Warwick IronWorks, within its limits. In 1860
the line between East and West Nantmeal and Wallace was slightly changed, and
East Nantmeal was altered at its western end, adding a part of Warwick to East
Nantmeal. These townships, which in former years were far removed from
railroad facilities, are now well supplied in that respect by the Wilmington and
Northern and East Brandywine RRs. *(1891)
