Salling's status is disputed. In 1991, William Marvel examined the claims of Salling and several other "last Civil War veterans" for a piece in the Civil War history magazine Blue & Gray. Marvel found census data that indicated Salling was born in 1858, not 1846. In the same piece, Marvel confirmed Woolson's claim to be the last surviving Union veteran, and asserted that Woolson was the last genuine Civil War veteran on either side.
