Niles City Directory 1912
The furthest we (Niles Library) go back is a 1926 directory. You could try the to contact the Niles (IL) Historical Society (http://www.vniles.com/195/Historical-Society). You can submit a "research request" through them @ http://www.vniles.com/FormCenter/Historical-Society-11/Research-Request-52. But, keep in mind the Niles Historical Society was only founded in 1971.
You could also try the Chicago History Museum (formally known as the Chicago Historical Society). 312.642.4600.
Thank you for your inquiry.
