Sterling's army documents give his middle initial quite clearly as "A." Most other sources use the middle name Seborn or Seaborn. The name gets mangled even more on the tombstone - Seabom S. Bobo. In addition, the army records show him in Company C, 48th Mississippi Infantry, while the gravestone's inscription has him in Company G, 41st Mississippi Infantry. I am not at all certain that these all refer to the same person.
