Jefferson Township, Montgomery County, Ohio was created on June 10, 1805 by the County Commissioners, from a portion of German Township. The Township was named in honor of Thomas Jefferson, one of the signers of the Declaration of Independence and the third President of the United States. Initially Jefferson Township was an extensive tract of land,
from which several present-day townships were formed. The Jefferson Township assumed its present form on August 21, 1841.

 Two villages, Liberty and Gettersburg were formed between 1800 & 1803, Gettersburg later changed its name to Ellerton

 Early Settlers & Settlements

 Following the Treaty of Greenville in 1795 and the ending of the wars with the Native Americans this region of the state was open for settlement. The first area in the Township that was settled was along Big Bear Creek, in the vicinity of Liberty, where John Gripe built his cabin. During this period 1797 - 1803, John Miller; George & Fannie Hoffman; Michael Weaver; Jacob Miller also settled in the area. Jacob Mullendore originally settled Gettersburg in 1802.

 In 1815, Liberty was laid out and platted and had a population of 225. The land was owned by Peter Becher. Liberty is the oldest town in Montgomery County.
