Barbara Lee Rowe, a fourth cousin of Elvis Presley, has opened a store called "Kin of Rock and Roll" in Gettysburg, Pennsylvania (here's the website). Her aim is to commemorate Presley relatives who served in the rebel army, and to sell some "decorative plates, candle holders and T-Shirts."
In a black binder with shiny silver text saying "Elvis' Family," Rowe has pages and pages of enlisted Presley kin from the Civil War. But she's proven Elvis' connection to only some of them, like Darlin Presley of the 26th North Carolina, who fought in Pickett's Charge and was taken prisoner. He later died at Point Lookout Prison in Maryland.
Horton Presley, of the 55th North Carolina infantry also served at Gettysburg and is related to Elvis.
"Confederate Americans are Americans too," Rowe said. "He knew he had Confederate ancestors and he was proud of it. But he was also proud to be an American. He would have put it in the proper perspective." [Link]
