I bought a slim booklet, barely legible mimeographed pages actually, with a title like "The Six (or was it Eight?) Black Presidents of the United States" in a little shop on 125th Street in Harlem in the late '80s or very early '90s.

The author, whose name I can't recall, claimed the current president was part black, but wouldn't name him. I assumed he was referring to LBJ based on the age of this little pamphlet. The claims sound a lot like those in your links . . . particularly the stuff on Harding. It's all very interesting but not very scholarly.
