Is it in Lincoln, Illinois, but the original building burned and was replaced by one that was demolished and parts used in other buildings???
I'm not up on Lincoln history, but I remember someone saying something like this years ago. Maybe Ed Steers or Joan Chaconas, both of whom have traversed the Lincoln Trail.
P.S. Ed is so dedicated to the Lincoln Trail that, when he built a retirement home in West Virginia, he got to name his street and named it Lincoln Trail.
