I recently found a Lieutenant William Thomas Jones Company C 35th NC. (Moore County). Free Man Of Color. One of the Immortal 600. Son of a slave and her white owner. Following the war, he was a highly successful entrepreneur, and basically restored the economy of Carthage, NC. The records for these men are certainly out there.
