Hi: I am descended from John Cass McGarity (1848-1910), my GG Grandfather and Dr. Abner E. McGarity's brother. Dr. Abner McGarity was the oldest child of John and Mary Embry McGarity and I have a copy of the book, Letters of a Confederate Surgeon, Dr. Abner McGarity. It is a goldmine of McGarity family information in its footnotes. I could have it reproduced if no longer available from GA State archives. I have all this stuff in Family Tree for Windows file also.
