I do not know much about the many Reed families.However, I do know Chief William Reed was a full blood Indian.In the book Passports to Georgia you see him going in and out of what was then Indian land.
Also an Alexander Reed claimed land inbehalf of his Indian wife in Tenn. around the 1800 time frame.
There is a Reed cemetery in west Tenn.I think it is in Gibson Co., but am not sure of that.
I have been looking for the parents of Elizabeth or Eliza Reed who was born in North Carolina or Georgia in the 1765 year range.Some say she was a full blood Indian. Others say her fatger was a French traper and her mother was an Indian.she supposedly married Elisha Fly. where I do not know.
