History
Norborne Parish was formed in 1771 from old Frederick Parish and named for Norborne Berkeley, a popular Royal Governor of Virginia. Originally it included the present counties of Berkeley, Morgan, and Jefferson. The first vestry included many who figured prominently in the Revolution and the settlement of the West, including the founder of Martinsburg, Adam Stephen, George Washington's brother, Samuel Washington, Thomas Swearingen and Morgan II. The first Trinity Church was built of stone in 1776 and stood at the corner of South Street and Maple Avenue.
