Hello List, I am trying to find information about a park in Des Plaines that the property was originally donated by the BIERMANN family. The family is my 2nd great-grandparents. My father has been there a long time ago when traveling. It's my understand that the local historical society was going to be taking over the property. If any one knows anything about this park or how to contact the historical society (or if they have a web page), I would greatly appreciate it. Thanks in advance, Mary Biermann-Rathburn
