Terrell, the info I have on John Black & Jane Alexander comes from an article on the history of Blacksburg Va published in the Roanoke Times in 1944. It says that John Black was the son of the Rev. Samuel Black of whom I am descended by the Rev's son Samuel JR. It also said John married Jane Alexander. I know of one son,James, who is probably the one who married Catherine Black, the daughter of Samuel Jr.making them 1st cousins. Your John Black and his brother William (who married Mary Black & not a Jane)were the founders of Blacksburg Va. Please feel free to e mail me.
