Do you have any suggestions of what to look for in MI? I have looked at a lot of websites, but don't have a subscription to archives. From what I can remember, The Detroit Free Press and The Detroit News were the big newspapers around at the time, but I don't know how far back they go online. ....
The Detroit News and Detroit Free Press go WAY back, but on line stories probably only go as far back as the 1980's or 90's. You might need to be a paid subscriber to get into their archives, but maybe not - Each online newspaper is different in that regard.
The Flint Journal is another main newspaper, and Lansing's State Journal is another.
There are also a large number of (Michigan) County newspapers which used to be weekly papers, but now come out several times a week. Many of those papers are published now by the Gannett Corporation.
