I've a ggggrandfather who served in the Revolution in the Pennsylvania militia. While other researchers have come up with the idea he was at Valley Forge, the best I can determine is he may have commanded a company of York militia guarding prisoners from Burgoyne's army.
Kenneth Roberts wrote some popular historical fiction about the Revolution, and Washington Irving wrote a two-volume bio of George Washington, both of which praised the "Virginia riflemen", often under Morgan. But J.L. Bell at Boston 1775 suggests cautiously that history may have gotten it wrong, that there were more Pennsylvanian riflemen than Virginians.
