Julie - From what I've read Warren's mother was a slave on the Coleman plantation (Daniel Coleman, I think) that was a neighboring plantation to the Barringers. Local history indicates that Gen. Barringer assisted Warren in his efforts. There's quite a lot of documentation on Warren as he was very successful and especially for his race and time in history.I'm from the Coleman line but "branch kin" to the line that Warren descends from. No kin to the Barringers, but if there is something that I can try to help you find, let me know. I have access to Cabarrus County records. I travel on Warren C. Coleman Boulevard quite a bit!
