John, take a look at
http://www.17thgeorgia.com/warroster.html which lists John (Ellis) Furgerson. In addition, I found a roster of Company K, 17th Georgia online in 2000 that was said to have been included in the "Minutes of the Terrell County Camp of United Confederate Veterans, Organized the First Tuesday in September 1893 and Enrollment Book" -- it listed a Ellis F. Furgason of Terrell County who joined on 3 March 1862. Tom
