I think my question has been resolved and my great-grandfather served in Hawpe's 31st Calvary which had been dismounted by the time he enlisted therefore his description of it as Infantry. I base that on the two witnesses on his pension application from "Co. A of the 31st" while he was in "Co. H of the 31st". Pemberton and Davis were both named in muster roll records for Co. A. Unfortunately, I have not been able to find any muster roll records for Co. H. I purchased some books about Hawpe's & Poulignac's men where I found a reference to the formation of Co. H from Dallas County in year 1863 with the "youngest being only age 15" from the Dallas newspaper story available on microfilm. That 15 year old had to have been my great-grandpa who was born in 1848 in Dallas County. This matches up with the family lore that he served from age 15 to age 17. There are no letters since he was illiterate and no photographs have been found. I haven't had a chance to go the the library and find that microfilmed news story to see if he was named.
I know it may sound strange that somebody age 53 (me) in year 2005 could have a great-grandpa who served in the Civil War. He married a second time in 1901 when he was age 53 to my great-grandma who was only 21 years old. Great-grandpa George had a total of 25 children between two wives and died in the 1920's. His second wife, my Great-grandma Jennie Cade Tucker died at age 104 in 1984 - widow of a Civil War Veteran 119 years afer the war had ended.
