Mr. Miller,
The second message in this string is a link to noted in "Tennesseans in the Civil War." It was published in the 1960's in "Tennesseans in the Civil War" by the Tennessee Historical Commission. Company D does show as a Stewart County unit in "Tennesseans in the Civil War".
Respectfully,
Gerald D. Hodge, Jr.
