I don't know if our families connect or not, but my Isaac Alexander married Mary Barber. They were on 1840 census Jefferson Co. AL and on the 1850 census Lafayette Co. AR. I have never been able to document where he was born but some relatives say it was in TN. He was born 1814. For a long time I have bene searching for his parents and siblings, also for Mary Barber's. I descend from Isaac and Mary's son Jesse Barber Alexander. Their other children were William, Nancy A.M.J., Mary B. and Isaac Jr.
