Located on the western edge of the Chesapeake on the main road between Alexandria and Philadelphia called the Old Post Road, the village at Halls Cross Road remained small until the Philadelphia, Wilmington and Baltimore Railroad scouted the area for a watering station in 1835. One of the railroad companies engineers was Edmund Law Rogers who saw the great potential in the place for development.

Village of Aberdeen

The Village of Aberdeen was a development by Edmund Law Rogers around 1800.[2] The name originated from its mother city, Aberdeen, Scotland, as a result of the close relationship the Rogers family of Baltimore had with their cousin, the Earl of Aberdeen, who became Prime Minister of Great Britain in 1852.[4] The area now known as Aberdeen is a cluster of three communities[5][6]
