In 1774, a Virginian militia group even attacked and captured the Westmoreland County seat at Hannastown and arrested three Westmoreland County justices who refused to acknowledge the jurisdiction of Virginia. Similar conflicts between Maryland and Pennsylvania had been resolved earlier, by 1767, through the work of two men chosen by Cecil Calvert, brother of Charles Calvert, 5th Baron Baltimore, proprietor of Maryland, and Thomas Penn and his brother Richard, sons of William Penn and proprietors of Pennsylvania.
