Just because he doesn't have a service record does not mean that he did not serve. I recently did some researching for a historical group of a man with no records that I could find. Yet, they had a Letter dated May 1864 from the 1st Sgt of his company to the man's wife explaining how the man died in battle and where he was buried. Interestingly whoever had transcribed the letter have mis-identified both the 1st Sargeants and the dead soldiers names. Not hard to do when you are trying to read their style of handwritting of that period.
The letter named several men who were wounded in the same battle or who helped bury this soldier and every name showed up in the same company as the 1st Sargeant and even the man's brother, who was NOT named in the letter. I have no doubt that the man served. But even his corrected name was not in the CSR's of Company "A" of the 26th Arkansas Infantry and no other "Official" records have surfaced.
This is just one of many such men that I have researched.
