I haven't got that far. I initially bought the book for the references in it (Of which Jack Cashill made me aware) regarding Frank Davis expertise in Photography and his interest in taking Photographs of nude women. After finding that section, I've been reading the rest of the book from time to time. I'm at the point where Frank is leaving Chicago. If he does go silent regarding the Hawaiian period, that is indeed strange and interesting. I think he was much more overt about his communist activities while in Hawaii, and he probably doesn't want to shed any light on that period of his life both for his own liabilities and from the possibility of harming his group or contacts.
Frank Marshall Davis’s post-humous biography ‘Livin the Blues’ is very detailed in the years before he moved to Hawaii (in 1948 if my memory is correct), and is almost non-existant after 1948. I wonder if he wrote anything about these years or if it was deleted by whoever published it 1992.
He did mention on pg 333, that he impregnated three white woman.
My guess is that the three white woman impregnated are: Helen Canfield, Madeline Payne (resulting in Barry) and Ann Dunham (resulting in Maya).
