I have noticed that you wrote Hizel for one of the names.It actually was Hisel.There were 2 in the 194th.One was Anthony T. Hisel and the other was William C. Hisle.
Smitty was probably a nickname for Smith.There were quite a few Smiths.Alvin Smith Jr., Andrew Smith, Bernard E. Smith, Bert P. Smith Sr., Buford L. Smith, Burman H. Smith, Carl G. Smith Sr. (died), Charlie A. Smith, Cleuts B. Smith, Cloyce P. Smith, Donald H. Smith, Eugene Smith, Francis J. Smith, George T. Smith, Gilbert L. Smith, Hawley D. Smith, Herbert A. Smith, Ira E. Smith (killed), James L. Smith Jr., John A. Smith, John C. Smith, John D. Smith, John E. Smith, John R. Smith, Joseph B. Smith, Joseph V. Smith, Levert L. Smith Jr. (KIA), Lonnie V. Smith, Milton H. Smith, Paul F. Smith, Peter A. Smith (KIA), Richard A. Smith, Richard R. Smith, Robert C. Smith, Robert M. Smith, Robert W. SmithWayne H. Smith, Willet J. Smith, William A. Smith Jr., William C. Smith Jr., William D. Smith, William E. Smith, William S. Smith and Willis C. Smith.Phew!There weren't as many Smith's in the 193rd as the 194th.I assume your Gpa was in the 194th?
As for Crawford, there were 2.Arthur C. Crawford and Arthur D. Crawford.
Gallagher's were: Alfred A. Gallagher, James P. Gallagher, and R.F. Gallagher.
If your Gpa recognizes any of the first names, then I can help you search for them.
Or if you discover that he was in the 193rd, I don't have as many matches and it would be easier.
By the way, what is your Gpa's name?I could find his name on the roster too.This would let me know for sure what he was in... the 193rd or the 194th.
