 Schematic History of 

 Mercer County Townships

Compiled and contributed by John MacDonald

If, for instance, you find your ancestor in Mill Creek Township in 1880, in French Creek Township in 1840, and in Sandy Creek Township in 1810, you can see by this diagram that the ancestor never moved, but rather that the Townships changed.
