Hi Jon, I would love to know about Botetourt Jacob Black. Please do post any leads you can pass along.
Sorry I confused you with the article. I am fairly sure that Jacob is the brother of Catherine, son of Botetort Jacob. If Jacob senior was still alive, in the 1820s, I believe that he traveled to IL with the Kessler crew.
I can also tell you that the folks in Illinois really don't know about the man they honored in IL.
