Mr. Madden,

For a short capsule history of the regiment, please see the link below.

Normally, "Tennesseans in the Civil War" included the company names if they existed. Another source you may want to check is the first roll of the Compiled Military Service Records and in the first several introductory cards they have the Company nicknames.

I hope this helps.

Respectfully,
