"Running within and without the breadth of the Monongahela, Allegheny, and Ohio Rivers, the territory (at least in part) consists of the parent area of the Pennsylvania counties of Washington, Westmoreland, Beaver, Greene, Allegheny, and Fayette; and the West Virginia counties of Monongalia, Ohio, Brooke, Hancock, Marshall, and Wetzel, though indeed much of the Van Voorhis work is concerned with Monongahela City and its farher reaching environs"--Forew.
