History
The Township of Derry was incorporated on August 1, 1729, when Lancaster County partitioned its territory for tax purposes. At that time, the boundaries of Derry Township were much larger and included what are currently three other townships within Lancaster and Dauphin counties.
The first official government in Derry Township was established in 1759. Five officials were elected for one-year terms. The number of elected officials in Derry remains five, although the terms are now six years.
In 1767 the court ordered the division of Derry Township, the eastern section to remain Derry and the western to be Londonderry Township.[4]
Derry and Londonderry became a part of Dauphin County when it was established in 1785. In 1787, the township's population was 198. Conewago Township was created in 1850 from southern parts of Derry Township and eastern parts of Londonderry Township.
The Derry Session House and Enclosure and Quarries of the Hummelstown Brownstone Company are listed on the National Register of Historic Places.[5]
