We put Rock Island in parentheses because the unused card itself does not give the location, really only telling us that Col. Davenport “was murdered in this house July 4, 1845” and that “Picket fence marks the site of his original grave.”  The Colonel in question is George Davenport, a settler, fur trader, and mediator between American Indians and the U.S. Government.  And don’t feel badly if you don’t see the picket fence.  We don’t, either.  Grade: 1
