Gettysburg bullet and its victim shared a postwar history

My great-grandfather, George W. Harrell, fought with the North Carolina troops at Gettysburg. He was shot in the upper part of his torso (maybe his back), and walked back to Elizabeth City. The bullet could not be removed. Years later, he experienced pain in his leg where the bullet had traveled. The now misshapen bullet was removed and kept as a family heirloom. I saw it when I was a child.
