George,
I checked the regimental history by Wallace Cross for the 14th TN - and a Norfleet (there were several in the regiment) and a Neblett (also several) were both in Company H. Other men with the same names were in different companies.
Norfleet was also only a private - so he too must have lost his re-election bid for LT.
So perhaps Co. H of the 14th TN is the Montgomery Guards.
