In the 1840 census, Dayton is not identified by name, but is not hard to locate. At the bottom of the last page of the La Salle County section, John Green’s name appears third from the end. The names surrounding his are mostly familiar names that appear frequently in the village’s history. But the name immediately above John Green’s is Joseph E. Skinner, who does not appear in the later history of the village. A newspaper search found this:
This explains why he appears next to John Green in the 1840 census, but where did he go later? Upon investigation, it appears he spent only that one year of 1840 working in Greens Mill.
Here is another case of someone with a Dayton connection who went on to greater things in the larger world. The short notice above hinted at later adventures which were written up in one of the county histories. That information has been added to the biography page, which you can read here.
