I am descended from Alexander M. McKINNEY and Phoebe RIFFE through their daughter Sarah. Do you know who Alexander's father was? You said in your posting that you had the McKINNEYs through 1659 and the Hatfields back to 1600. Do you have your trees online where I can see them? Or can you send me a gedcom? I'd sure be interested!
I also love to have a list of Alexander and Phoebe's children and their spouses.
