I attempted to do a look up on this, but I could not find anything on the names that you were looking for. A couple of questions, first were they regular army or militia? I suspect that they may have been regular army, oh by the way, are you sure they served in the Illinois Black Hawk War? just so you are aware, there was another conflict called the Black Hawk War in Utah. If you get anymore information, Ill see what I can do, or point you in the right direction.
