OK, so for a while now Vivian's kind of had me stumped. It's like the more I learn the less I know. I'd been thinking that maybe Vivian Davis wasn't her maiden name. The marriage certificate to George Chase listed her maiden name as Vivian Davis from KC, MO and her age as 19. I can find Vivian Davis earlier in that year (1920) in the census as a single waitress in KC, MO. When she was booked for her fight with Mrs. Flournoy in 1926 she listed her hometown as Springfield, MO. Now, I've looked for Vivian Davis in Springfield and I found one. But she died in 1920 at 15 years old.
Vivian was most likely born around 1901; unfortunately, birth certificates were not required in MO until 1910. (For now, I'm sticking to MO as a birth place) The MO state archives has a wonderful website with digital vital records and indexes for the period before 1910. But no luck. I'm more than likely going to need to travel for what I'm looking for in KC (school records and such)to determine if there was a Vivian Davis who at school there during the right time period. That is going to have to wait for a while until I can afford to get away. So while I'm waiting to pursue that angle I'll see if I can't find another Vivian in Springfield during the right time frame. I found some old school records online so.... It's just one possibility and it won't hurt. Might not help but it won't hurt.
