Many thanks, Alan. (Oh, the joys of trying to reconcile info in NPS Soldiers and Sailors roster! Works best when one already knows the answer.) Routh was in school at UNC (Chapel Hill, NC) 1858-1860 (Soph in 1859 at c. 19), but has no record of graduation. I was trying to account for his presence during the interval leading up to his enlistment (and perhaps account for his choice of unit, whether he enlisted in MS or VA, whether he became involved with signals on detailed basis or was selected "cold" for commission and the like -- all to get a better "handle" on him). Jeff Davis Legion is a bit tricky for me.
