Have found Axel Olsen / Olson, possible relative, at this address in Chicago City Directory for 1884 and 1885. Would anyone know where this address might be today. It was listed as a house. The 1909 address changes does not show anything as low as #40 Cornell. Also the Cornell in the directory for 1884 and 1885 does not say whether it was a street, avenue, etc. Thanks, Mary
