3) George Nixon. Civil War Union Army Soldier. He served during the Civil War as a Private in Company B, 73rd Ohio Volunteer Infantry. During the second day of the Battle of Gettysburg (July 2, 1863), he was wounded in the right hip and side during skimishing with the Confederates, and lay in the no-man's land between the Union position on Cemetery Hill and the Rebel's hold on the town. At night his cries of pain were such that it inspired Private Richard Enderlin to crawl out during the constant firing between the two forces, drag Private Nixon back most of the way, then stand up with the wounded man in tow and dash the final distance to safty. This act won Richard Enderlin a instant promotion to Sergeant, and a Medal of Honor 34 years later. Despite his rescue, Private Nixon's wounds proved to be mortal, and he died in the XI Corps Hospital seven days later. His great-grandson, Richard Millhouse Nixon, would become the 37th President of the United States.

Although his more brilliant achievements took place after that time, he had been by no means inactive before, having served in the Bull Run Campaign of 1861 as an aide on General McDowell's staff, and afterward in the operations at Key West, Florida; Hilton Head, South Carolina, and in the battle of Pocotaligo in South Carolina. He also participated in the attacks on Charleston and the bombardment of Fort Sumter.

He was brevetted a Major for distinguished gallantry in the Civil War.
