Millersville, named for the first Postmaster, George Miller, was the first Post Office to be established, on July 24, 1841, along the Annapolis & Elkridge Railroad (the A & E). Completed in 1840, the A & E was one of the earliest rail lines in the U.S., connecting Annapolis with the Washington Branch of the Baltimore and Ohio Railroad. Today, Millersville is largely suburban, but the core of the historic village remains. The Childs Residence, listed on the National Register of Historic Places in 1986, is a focal point of the new bike trail that passes through the historic core.
