HI: You would probably find a lot of new info in the book "Letters of a Confederate Surgeon: Dr. Abner Embry McGarity" published in the 1940's. I have a copy. Pls check the Georgia State archives, etc. for availability, or else I could try to have it reproduced for all interested. My GG Grandfather was John McGarity (1807-1893) born in Elberton, GA. Numerous of his children either fought in or were married to soldiers of the Civil War. This book is a wealth of info re this. Dr. Abner McGarity (1832-1915) was one of John's 11 children, and Dr. McGarity was my G Grandfather's (John Cass McGarity 1848-1910) brother. I keep track of all this on Family Tree for Windows. Gardner McGarity does not ring a bell with me.
