This vast territory can be characterized in two important ways. First, as the frontier. Second, and just as important at the time, the territory can be described as the part of Virginia populated by newcomers who were for the most part neither English nor Anglican. Unlike Pennsylvania, most of Virginia was very homogeneous. Nonconforming churches were illegal, but tolerated west of the Blue Ridge. Despite belonging to the same denomination as the last two kings of England, Peter Muhlenberg had to go to London to be ordained in the Church of England in order to preach in Woodstock as late as 1772. (Four years later he became the regiment's first colonel.) In describing the 8th Virginia as the "German Regiment," the Virginia Convention really meant the "non-English" regiment. Culturally, the Irish and German men of the regiment had more in common with Pennsylvania than with Piedmont and Tidewater Virginia.
Winchester's Daniel Morgan was a true hero of the Shenandoah Valley, and he is rightly famous. However, the units he led were not true Shenandoah Valley units the way 8th was. In 1775 he was a captain in the Virginia and Maryland Rifle Battalion; in 1776 and 1777 he was colonel of the 11th Virginia, which recruited from Frederick County but also from Prince William, Amelia, and Loudoun counties; his famous Virginia rifle battalion, formed in 1777, was built on merit, not geography.
Only the 8th Virginia truly represented the geography and the culture of the Shenandoah Valley.
