I believe there is ONE AND ONLY ONE reallife historical person explicitly named in the entire GF Trilogy:

Fidel Castro

...in GF2 when the rebels yell "Viva Fidel" before they blow themselves up. Otherwise, they only implicitly name the generic titles of "the President" of Cuba in GF2, or the "Pope" in GF3.
