Looking at census records, I see the spouse of George Gordon Yawn with children George V and Billie, listed as Demaus, Demarious Demarionis G Yawn, Also listed as Gordie and Geordie Yawn. It would be nice to see a birth certificate with the name on it. I can see where Demarious etc could have been shortened to Mary, makes sense, and of course Gordie and Geordie could turn into Gertie. I am not sure of the source of Gertie, but it's possible the census taker screwed up and wrote Geordie and Gordie. Still trying to find who her parents were too. I have been down to the Palmetto Cemetery and the stone reads; Mary Gertie Meeks Yawn.
