Excellent research on your part.
Darold Leigh Henson, Ph.D., is pretty much a legend in my hometown for the tome he created, regarding the history of one- Lincoln, IL.
That was an interesting site. It was a little frustrating because I started reading just wanting to know what happened to the original Postville courthouse, but the site went into the entire story, Henry Ford and then the building of the replica.
Is Postville still a town, or did it become Lincoln, Ill.?
