Charles F. Weller enlisted in the 15th Pennsylvania Cavalry in 1862 when he was 17 years old. Charles was on active service until the end of the war, campaigning in Virginia, Maryland, and Tennessee. He marched with Sherman, was in Captain McAllister’s Company “G”, and fought in Hagerstown. Weller participated in the Battle of Antietam and the Battle of Chickamauga among many. While Weller was a soldier in the Civil War, he wrote 50 letters to his girlfriend, Kate McElwain of Beaver County, Pennsylvania. Weller mustered out on June 21, 1865 and received an honorable mention for his meritorious service and soldierly conduct. Weller married McElwain soon after the war, and eventually settled in Omaha, Nebraska.
