Barclay Coppock (January 4, 1839 – September 4, 1861),[2] also spelled "Coppac", "Coppic", and "Coppoc", was a follower of John Brown and a Union Army soldier in the American Civil War. Along with his brother Edwin Coppock (June 30, 1835 – December 16, 1859), he participated in Brown's raid on Harpers Ferry.
Edwin and Barclay Coppock were born of Quaker parentage in Winona, Ohio, near the intensely abolitionist town of Salem. After their father died early in their lives, they were raised by John Butler, described as "a benevolent Quaker",[3] who has left us his recollections of Edwin.[4] In 1857 Edwin was expelled from the church, as he refused to give up dancing.[5]: 196 As teenagers they moved to Springdale, Iowa, where their mother was living. It was here that they met John Brown as he passed through in early 1859, transporting people who had been enslaved in Missouri to freedom. That summer, the two boys bade their mother goodbye, despite her fears of the violence they would encounter, and traveled to Chambersburg, Pennsylvania, to meet Brown's growing army.[6]
