1. Devore’s ferry in 1784 connected Westmoreland and Washington counties; in 1788 the northeast landing of the ferry became part of newly formed Allegheny County while the southeast landing remained part of Washington County. GW apparently did not realize that he had crossed from Fayette to Westmoreland County near Col. Edward Cook’s house on 18 Sept. (BUCK description begins Solon J. Buck and Elizabeth Hawthorn Buck. The Planting of Civilization in Western Pennsylvania. Pittsburgh, 1939. description ends , 172; ALLEGHENY description begins Thomas Cushing. History of Allegheny County, Pennsylvania. Chicago, 1889. description ends , pt. 1, 120).
2. Adam Wickerham of Washington County, a German immigrant, lived on the bank of the Monongahela near Devore’s ferry. According to tradition, he avoided arrest during the Whiskey Insurrection of 1794 by feigning idiocy (VAN VOORHIS description begins John S. Van Voorhis. The Old and New Monongahela. 1893. Reprint. Baltimore, 1974. description ends , 165–67).
