I have Ackles in my family too. My grandfather is Estus Bruce Ackles, son of Stephen William Ackles and Isabelle Rhodes. Stephen was born in 1875 (about) and Isabelle was born about the same time in Springfield. That is also where Stephen and Isabelle married.
I can't seem to get William Stephen Ackles who would of been Stephen's father. I am thinking that he was born about 1840 in Linder, Christian Co. Missouri. But can't pin point them there.
This is the first time that I have tried to search out my great grand parents so I don't know if you have that information or not. Seems to me that we were told at one time that James was the patriarch of this family line but am not sure of that either.
