Hi, I'm probably something like your 5th or 6th cousin, Jackie.
I am of the opinion that the first Isaac, Bennett and Caleb in Alabama - the ones who bought property in the late 1830s, were brothers, or maybe cousins. (It doesn't help that they all named their children after each other.)
Isaac W. was born about 1788. I've seen it posted that Bennett was born about 1897, so I don't think Isaac W. was his father.
