The Highland Park Public Library has a web site. You can find it by typing in Highland Park Public Library, click on Explore Highland Park, then Local History and finally Highland Park Local History. There is a picture and short description of the original Railroad Men’s Retirement Home. I have the following information from the 1930 U.S. Federal Census, Lake County Illinois, Deerfield Township, Highland Park Illinois taken April 12, 1930, Enumeration District #21, at the Railroad Men’s home located at 929 South Saint Johns Avenue.
