Millerstown is located on a tract of land originally sold to James Gallagher on September 23, 1766, however, there is evidence that a small town named "Smithfield" was founded by him before then.
This plot of ground was later sold to David Miller on September 1, 1780, who filed for a patent in 1790 for the "laying out of the town," thus making Miller's Town the first town to be plotted for sale in the territory at that time comprising Perry County. Miller's Town was later combined to form Millerstown.
Millerstown Borough was incorporated February 12, 1849, and the first meeting of the newly formed town council was held on April 14, 1849. Abraham Addams was the first chief burgess (mayor), and John M. Cauffman, Christian Beck, James R. Gilmer, and Jacob Emerick, were members of the first Borough Council. Thomas P. Cochran was the first council clerk with a salary of $2.50 a year.
Today Millerstown is home to many old stone houses, some dating back to the 18th century.
