From King's Mountain and Its Heroes: History of the Battle of King's Mountain, by Lyman Copeland Draper, pub. 1881, P.G. Thomson:
Joseph McDowell, Sr., of Scotch-Irish descent, was born in Ireland in 1715—reared a weaver, married Margaret O'Neil, and early migrated to Pennsylvania. He soon after settled in Winchester, Virginia, where his sons, Charles and Joseph, were born—the latter in 1756. A brother of the elder Joseph McDowell, known in after years as "Hunting John McDowell," early removed to the Catawba Valley, settling that beautiful tract, Pleasant Garden, sometime prior to 1758; and at some period not very long thereafter, his brother Joseph McDowell, Sr., followed to that wild frontier region, locating at the Quaker Meadows, where his family was reared.
Joseph McDowell of Pleasant Gardens, Burke County, North Carolina was my 4x great-grandfather. Extensive genealogical research on my mother's McDowell lineage has prompted me to offer corrections to Lyman Draper's misstatements regarding the various related Josephs McDowell. Draper's confusion is understandable in context of the numerous close relatives who shared the same name and served their country one way or another in the early years of the American republic. A re-write of the Draper excerpt may help to clarify the genealogy:
Joseph McDowell II, of Scotch-Irish descent, was born in Ireland in 1715—reared a weaver, married Margaret O'Neil, and early migrated to Pennsylvania. He soon after settled in Winchester, Virginia, where his sons, Charles and Joseph III, were born—the latter in 1756. "Hunting John" McDowell, son of the elder Joseph's own brother Charles (born c. 1697), early removed to the Catawba Valley, settling that beautiful tract, Pleasant Gardens, sometime prior to 1758. By 1762, Joseph McDowell II followed to that wild frontier region, locating at the Quaker Meadows, where his family was reared.
