A years work down the toilet. Evidently, I have been completely and utterly wrong. There's no way that the Vivian Davis who married George M. Chase in 1921 is Vivian G. Davis of Springfield, MO. That Vivian died a year and a month before the wedding!
Time to take another look at the sources or perhaps I could interest one of those mediums, who are always bothering dead people, to visit the graves and find out the truth from the source.
I have learned a valuable lesson. I will never trust someone else's research at face value. I will always do my own or verify as if it were my own. Truthfully, piecing together someone's information from old census records when they have a common name is not easy. It is easy to trip up when you can't find everything at once i.e. birth, marriage, and death data scattered everyplace. I just have to look at this as part of the process and not give up.
