Check the online Chicago Tribune. Some Chicago newspapers published lists of marriage licenses issued during some, but not all, years. If you find a name there, but can't find it in the index to get the license number, check the index for a name just above or just below. The newspaper lists appear to be in issue-order and the license number can be deduced if can find one for another name on the list.
