My ancestor was Nimrod J. HUGGINS, b. c1833 in NC. Lived in Fannin and Union Co Georgia.

On Ancestry.com I found two Civil War "records". Both indicate he was inducted and discharged as a Sergeant (Confederate).

1. Nimrod Huggins, Co B, 6 Georgia Cavalry
2. Nimrod J. Huggins, Co B, Smith's Legion, Georgia

What do these records indicate? Where can I find more information about his service? these units?
