Cass County where Kimbrough was from became Bartow County in 1861 but a lot of people still called it Cass County. Gordon County came from the top of Cass county and the bottom of Murray Counties. George was from the lower part of Gordon County which was Cass County.
His letter states that he "joned the first of the wore in '61". On his CMSR the dates say 4 Mar. 1862. This was also his birthday. But.........
