John W. Peake was born around September 1845 in Virginia to Joseph and Mary Peake. His father was a wagon maker who owned $479 of personal property by 1860. He grew up in Fauquier County, Virginia.
He enlisted in the Confederate army, and he mustered in as a private in Company A of the 6th Virginia Cavalry. According to his service records, he was 5 feet, 4 inches tall, with brown hair and hazel eyes. The regiment took part in the Seven Days’ Battles, the Second Battle of Manassas, the Battle of Antietam, the Battle of Fredericksburg, the Battle of Chancellorsville, the Battle of Gettysburg, the Overland Campaign, the siege of Petersburg, and the Appomattox campaign. In April 1865, he gave his “parole of honor…not [to] take up arms against the United States Government.”
He returned to Fauquier County after the war and earned a living as a merchant. By 1870, he owned $850 of personal property. He married Alwilda Brooke on December 21, 1886, and they apparently had no children. They lived in Washington, D.C., and Peake worked as a real estate broker. He died in 1925.
