John Marr was born in Warrenton, Virginia, in 1825. He attended the Virginia Military Institute then settled in Warrenton where he was active in local politics. In 1859, after John Brown's raid on Harper's Ferry, he organized a militia company, the Warrenton Rifles, and served as a delegate to the Virginia Secession Convention.
In the spring of 1861 the company became part of the 17th Virginia Infantry Regiment and was stationed at Fairfax Court House where it was attacked by a party from the 2nd U.S. Cavalry Regiment in the early morning hours of June 1, 1861. In the skirmish Captain John Marr was killed, becoming the first Confederate officer to be killed in action. There is a monument to John Marr next to the old Fairfax County Courthouse and modern John Marr Drive in Annandale is named in his honor.
