Just a few things to get you started...

Start here with some of your names...you'd be surprised at what you might find:

If they married or divorced in Georgia, you can use this form to send for information on the marriage/divorce. If they married prior to 1952 and it was in Georgia, the divorce record will probably list the county they married in and then you can send to the probate judge in that county for their marriage record.

If you think your father may have passed away already, you can try this link to search for his obit in Michigan...you might need to change the settings a bit to All Michigan Obituaries, All Time, and plug in whatever name you're searching for (this link allows all USA searching)...also try the Michigan Death Index on Ancestry:

There are many other routes to ferret out more data, but this will hopefully get you started. It can be frustrating and slow going sometimes, but don't give up. The info is out there somewhere.
