I assume this is he, Wayman Wolfe. If born in 1819, he would have reached Conscription age of 50 February 1864 at which time he may have enlisted in the 25th Virginia. However, muster rolls through December 1864 exist and his record is missing. This could indicate that he may have enlisted early in 1865.
