I am hoping if someone goes to the Naperville FHL (Or elsewhere) could see if they could find the marriage of Oscar A. Jensen born Feb 1882 Norway, died 8 Jan 1909 Chicago. He married a "Minnie" about 1905 and had one son Donald Jensen Sr. born about 1906 Chicago. IN the 1930 census Minnie Grarke is listed with her son Donald and his wife Lorraine, last name enumerated as Jansen, she may have remarried and became widowed again. There is also a thought that Minnie's maiden name was Krause, but not confirmed. Any help is greatly appreciated. Laurie
