John, My source for Nathan's age was his service record.Many times I have found these records to be incorrect as to age.
Co. L of the First Alabama was recruited by Lt. Sanford Trammel with the help of Jeremiah Files of Fayette County, Green Haley of Marion County and others.The records of everyone who joined Co. L show that they enrolled at Fayette County, AL on Sept. 25, 1863.That's the day that Trammel, Files and recruits from Fayette County started a journey northward toward Glendale, just outside of Corinth.According to arrangements already made, others joined them as they went north,including a large group that met near Natural Bridge in western Winston County.This group included my great-grandfather.From there they continued to Allen's Factory (near the present site of Bear Creek in Marion County) where others joined them.Of course, from there, they went up through Franklin County, where Nathan may have joined them.Thus, Nathan undoubtedly did not have to travel south to Fayette County to enroll and it was probably a few days after Sept. 25 when he did actually sign up.
Shortly after arriving for their training in Glendale, many of these country boys got sick from what they then called "crowd poison."The fact was that they had no resistance to many diseases, such as measles and chicken pox, and in many instances these diseases were fatal to them.The reason Nathan was mentioned in the book is because he was one of the first ones to die after their arrival in Glendale.
It's a wonderful thing to be able to communicate with you when our ancestors were acquainted and perhaps even friends some 142 years ago.
