The Beilfuss Family of Winfield, Illinois

I am currently searching for links to my Grandfather (Otto Beilfuss) who came to the USA about 1909. He lived in the Chicago area after that. His father was Heinrich Beilfuss from Parsow (near Stettin) in Germany. Otto's siblings included Max, Bruno, Greta, Rose, Agnes and Heinrich. At the end of World War II the family left the East Prussia area (now Poland) and fled to the Hamburg area. More detailed information available on request.
