I have the cival war records of captain Richard Fields who is also in the 1866 photo. My great great grandfather is Richard F.Fields born 1823 Georgia and died 1879 Indian Territory. It took some time for me to figure out that their are at least two Richard Fields in the civil war. Richard F. Fields obituary states that he was a famous guerrilla fighter and scout. He was equally well acquainted with English and Cherokee. these two Richards are first cousins. Their are a couple more Richard Fields living in Indian territory at the same time.
