Prior to 1813, these townships were actually in parts of Chester, Lancaster, and Dauphin Cos., Pa. These tax lists cover East Hanover, Hanover, and West Hanover Twps. for the period of 1750-1783 and for the Londonderry area during the years 1775 through 1783. Residents petitioned the courts for boundary changes in 1736 and 1737, and again in 1768, requesting divisions and changes in boundaries due to "inconveniences by largeness of the township(s)." Residents living there were assessed and tax lists were created during this period. (128pp. illus. index. Masthof Press, 2007.)
