I am looking for information regarding my great grandfather Anton Sikorski (born 19 Jan 1877) who immigrated from Poland and was living in NJ first then moved on to Chicago. He passed away 5 Oct 1925. His sons were Victor (1916 - 1965), Chester (1913-1985), and Edward (1908-1989). I know that Chester married a woman named Betty and had four kids but I know nothing about them. I assume they are all in the Chicago area if still living. Any help would be greatly appreciated.
