The family migrated west across the Blue Ridge Mountains to settle near Moorefield, Virginia (now West Virginia) in 1758. In 1770, they moved farther west to the Tygart Valley. They began to acquire large parcels of virgin farming land near the present-day town of Buckhannon, including 3,000 acres (12 km2) in Elizabeth's name. John and his two teenage sons, were early recruits for the American Revolutionary War, fighting in the Battle of Kings Mountain on October 7, 1780; John finished the war as captain and served as a lieutenant of the Virginia militia after 1787. While the men were in the Army, Elizabeth converted their home to a haven, "Jackson's Fort", for refugees from Indian attacks.
