Does anyone have any good information on the wartime service of Private John H. Bush (8th Ala, Co. B) and Private Robert T. Bush (8th Ala, Co. B).

I have been able to determine that they probably enlisted at Wetumpka in 1862. However, I have not been able to find any additional information on their wartime service. There is also no mention of their names on any post-war Alabama census information.

I could not find any additional information on these two relatives during a recent trip to the Alabama Archives.
Their names were not included on the 8th Alabama, Company B Muster Roll. However, the muster roll in the archives was made many years after the Civil War, from memory by one of its former members.

Does anyone have any further information on these two people? Thank you very much for the help.
