Yes, I do have this information. Apparently he did not join the Confederate Amry at the beginning of the war, and he was not conscripted. Apparently he eventually decalared himself Captain of the 487th District, G.M., Dekalb County, Lythonia (now spelled Lithonia). GA ... this was March 20, 1862.
He is also listed as a member of "The Dekalb County Silver Grays" , 8th Regiment, Georgia Infrantry, State Guards, under the command of John Henderson.
This unit was moved near Savannah around September 1863 ... but the muster roll shows W.D. Abbett "absent sick" from September 10, 1863-January 6, 1864. Apparently he returned to the regiment in March 21, 1864 ... at which point he was promoted to 2nd lieutenant.
He returned to Dekalb county after the war. He was often said to be sick in the years leading up to his death in Nov of 1873 ... this might explain the long abscense from his unit? Oh, we'll never know!
He is buried at Macedonia Baptist Church (on Panola Rd)... but his grave marker reads "WaltEr AbbOTT ... this marker was not placed on the grave until the early 1900's though.
I am not sure when Walton's descendants changed the spelling of the name. My family currently uses the Abbott spelling of the name.
