I had a GG Uncle named William Jessie McClain that was Elgin Comanche Co. OK in 1940 when he was listed in his brother Obituary. I know he had been there for a time before that though. He had two sons Watts and Sydnor McClain. His wife name was Laura Kerce McClain. I think there was 3 girs also. I know there is one to many C in the name for yours but I find mine spelled both way. Do any of these names look like thay could connect? Oh by the way thay came from Rome Floyd Co. GA.
