Thomas, I believe we are researching the same family, though I am still trying to prove my connection to James Black Sr. It appears that another of his sons, Robert, married Elizabeth Jewell on 7 May 1803 in Barren Co., KY. I believe this same Robert and Elizabeth arrived in Wayne Co., IL by 1820 with 7 children. I have quite a bit of info from that point. Do you have any info on James Sr's children? Or on the apparent migration of a large number of residents from Barren Co., KY to Wayne Co., IL? I would be glad to trade information.
