Hi Jon and thank you,
My Jacob Black was the father of Catherine Black (b.1802) and the father-in-law of Daniel Kessler (Early marriages, wills, and some Revolutionary War records, Botetourt County, Virginia by Anne Lowry Worrell). These are my husband's ancestors lsited/cited/written about in Morris Kessler's "Out of the Blue Ridge."
Any primary sources or academic works?
Was Jacob Black married to Barbara Lark?
Did he serve in the War of 1812 and the Black Hawk War?
Is he buried in the Florey Cemetery, Ill http://mywebtimes.com/archives/ottawa/display.php?id=406770
