Input: Question: In what year did the area along the Ohio River where Moore was born become part of a new state? Passage:He was born in Lewisburg, Virginia in a portion of the state along the Ohio River which became West Virginia in his lifetime. His father had been born in Shenandoah County and moved across the Appalachian Mountains to the Greenbrier County area, but died when Charles was an infant. His paternal grandfather had married a daughter of Joseph Morgan, who helped settle the trans-Appalachian area. His mother, Augusta Delphia Page of Staunton, Virginia, a daughter of Major Charles Page, died in 1844 so Charles and his sister were raised by their uncle, George Moore in Mason County. When Charles was 16, he was sent to Marshall Academy in Huntington, and he would also study with John I Van Meter in Pike County, Pennsylvania, then attend Jefferson College (which later became Washington and Jefferson College) in Canonsburg, Pennsylvania. While at Jefferson College, Charles Moore helped found the Phi Kappa Psi fraternity before graduating in 1853. Moore then briefly attended Union College in New York. Returning to Virginia, he studied law at the University of Virginia and completed the course in 1856.
