Jeff, George Ancel Parker's daughter, Rosa Adell Parker (McGee) was my grandmother. Check Coosa county for the Armstrongs and I am almost certain that you will find George's family there also. According to my mother, Adell was part Cherokee and the Coker name is real familiar to me.
This is a very old post so you may have already found the data that you need. PS - My mother says the Parentine name should be Barentine but I am not positive.
