I wonder if perhaps we might be on the trail of the same McKees.
My father used to refer to his grandmother as Molly or Mollie McKee and that she was either full or half blood Cherokee. He described her as wearing a long braid.I believe she may have had two brothers, Robert and Jack, but I am not certain. Molly may not have been her real name, but instead, a nick name.
She had two daughters (I think) Blanche and Veda.Veda married Homer Knizley, and they had four children. My father is James Bradley Knizley.
This grandmother may have been my father's great grandmother rather than his grandmother. My recollections are scarce and I do not have any paper trail to follow.
If any of this rings even a slight bell, please let me know.
