Since Middletown’s official incorporation in 1833, it has grown leaps and bounds. Check out these maps from the MidPointe Digital Archives “Historic Butler County Atlases and Maps” collection (http://www.midpointedigitalarchives.org/digital/collection/p16488coll5), and see for yourself how Middletown has changed over the years!
Also, make sure you fill out the 2020 Census - https://2020census.gov/ and etch yourself into history. Just like these fine folks did in 1910, when the Census was compiled completely by hand and in person.
