This is a long shot, but I suspect that there might be a connection. A Manning Campbell died in Smith Co Tennessee in 1837, and his will was witnessed by a man named Brewer and a man named Tate. Several descendants of Manning Campbell subsequently relocated to Yell Co Arkansas and continued to live there for several generations. I would like to compare notes since I think that solving your Brewer/Tate lineage could help me solve my Campbell lineage. Several of the families associated with Manning Campbell in Smith Co Tenn came to Tennessee from North Carolina. I look forward to hearing from you.
