I have that the father of your William Koger is in fact Nicholas and Dorothy Koger. I have quite abit of info on the Kogers and would be willing to share what I have. I also have a picture of Charles Cagle Koger's brother William. I may also have a picture of Charles but I'm not sure. If you are still in need of Koger info send me your snail mail address and I will send you a little packet of info.
