"In 1999, Dr. McNelly stated that he had proposed to Frank Herbert that they collaborate on a Dune prequel novel, expanding upon the Butlerian Jihad story presented in The Dune Encyclopedia. He noted, "FH and I had discussed writing it together and he agreed with my general plot outline, completed first chapter, and so on but his untimely death prevented us from continuing." "
taked from:

And also reading the goggle group post of McNellis above, he confirmed that "the story of the aborted female fetus in the DE which brought about
the Butlerian Jihad, that creation was entirely my own,..."
So we could say that Bh&KJA stoled the idea for their Butlerian Jihad and Serena Butler's plot from McNellis, and not from FH notes??
This is a great discovery for me, because McNellis claimed that all the Butlerian Jihad origin and story from the DE came from his mind with the approval of FH. He already confirmed that he had a first draft of a first chapter of the "Prequel to Dune: Butlerian Jihad" wrote with the FH contribution.
Could some1 stole that chapter from the McNellis family?

Or we could believe that BH&KJA have this chapter too?
And, for ending: "I am not sure that FH meant any paticular "Butler." "
How can they say their novels is based on FH notes???
For me, all this history lay itself in a mistery...
