The following message was posted on the Gallatin County list. Hope it helps

You was asking about a man named Uncle Bob who was
supposed to be a slave in Gallatin County, Illinois.
We have a man named Bob Wilson in our family
background. Nobody called him Uncle Bob though. If
the Bob you are talking about used to live in Virginia
in the civil war time he just might be kin to us.
None of us ever knew about him living in any place in
Illinois cept in Chicago, Illinois. How are you kin
to Bob Wilson. Write some more information about the
one you are talking about.
