 Centreville's name was derived from the relocation of the county seat in 1782 from Queenstown to a more central part of the county.Saint Paul's Parish was established on the site that would later become known as Centreville, Maryland.It was almost 100 years later, in 1782, that the Maryland State Assembly passed an Act to relocate both the courthouse and all government functions of the county to Centreville from Queenstown, making Centreville the new county seat.
