I picked this book up a few years ago and found it quite interesting. It was written by a contemporary black woman with a Ph.D. in black history or something and partly based on J.A. Rogers booklet which was published under a similar title much earlier. J.A. Rogers, of course, is the great self-taught black historian/sociologist. The later book is a small press one that probably did have a substantial first printing. I saw it once in a black book store and never again anywhere else.
I found all but two of the arguments weak, speculative, mainly. Then, of course, there was Warren Harding, the worst President ever who particularly admitted he had a black ancestor: "I honestly can't say who my grand-daddy went to the woodpile with". And then the stunner - Dwight Eisenhower. The argument presented for him knocked me off my feet. I've been convinced he's black ever since.
The Eisenhower argument was presented straightforward enough. In the Virginia town he was born there were two "Links" families, a white one, and a black one. The question is, which one did his maternal grandfather come from? Eisenhower's maternal grandmother isn't suspect. Her lineage is lily-white as far back as you can go. But this guy who married, Eisenhower's mother had a child with her, then disappeared, is the one. Two other items about this case. Interviews made during the 50s uncovered some very old people who long remembered referring to Eisenhower's mother as "that black Links gal." These people asserted there was never any question about what she was. And finally, the most stunning piece of evidence: a picture of Eisenhower's mother on her wedding day. This picture is included in Eisenhower's auto-biography, "At Ease!" I dropped the book when I saw it. This woman would not have been able to eat in restaurants anywhere in the South before the end of segregation.
