Archibald Alexander was born at South River, Rockbridge County, Virginia, and raised under the tuition and ministry of Presbyterian minister william Graham (1745–1799), a man who had been trained in theology by John Witherspoon. His grandfather, of Scottish descent, came from Ireland to Pennsylvania in 1736, and after a residence of two years removed to Virginia. william, father of Archibald, was a farmer and trader. At the age of ten Archibald was sent to the academy of william Graham at Timber Ridge meetinghouse (since developed into Washington and Lee University), at Lexington. At the age of seventeen he became a tutor in the family of General John Posey, of The Wilderness, twelve miles west of Fredericksburg, but after a few months resumed his studies with his former Teacher. At this time a remarkable movement, still spoken of as "the great revival," influenced his mind and he turned his attention to the study of divinity. He was licensed to preach October 1, 1791, ordained by the presbytery of Hanover 9 June 1794, and for seven years was an itinerant pastor in Charlotte and Prince Edward counties.
