William Jefferson Blythe in 1944, said to be the real father of Bill Clinton, but he doesn't seem to look much like Bill.
My name is Tom Wakefield. Most years I attend the Wakefield family reunion in Hope Arkansas, birthplace of Bill Clinton. Many of my relatives are lifelong residents of Hope. I have heard it more than once, in casual conversation at these reunions, that the biological father of Bill Clinton is a doctor in town. "Everybody knows it" and "Bill Clinton looks just like him" are common statements made by my relatives. They speak of this in a way that it is just common knowledge around Hope. I do not know the name of the doctor, and I do not know if he is active or retired. (I doubt that he would still be active.)
But there can't be too many doctors in Hope. I think that this is worth investigating. Something I just thought about while writing this letter. Bill Clinton, despite his many faults, is a highly intelligent person, just like a doctor would probably be above average in intelligence.
