Frank, thank you for your help. His name was Nathan Benjamin Brooks, 26th TN Vol, Co. C. He served from 1861 to 1865. At one point he was transfered to Co. N as part of the 'engineers'. I don't know if Co. N was still part of the 26th. I assume the confederate engineers were similiar to the federal Pioneer Corps. His obit said he had been a ditch digger, carpenter and well digger. Sounds like he spent a lot of time at the end of a shovel. :)
Thank you again -- Ruth
