The �Nora' is not a woman's name but a form of the word �horror'. The phrase started off as "flaming horror" (or "flipping/bloody horror") as a cry of dismay/disbelief. In the normal Cockney manner, the final �g' and the opening �h' were dropped to produce something that sounded like "flamin'-orror" and that in turn over the years became "Flamin' Nora!"...or "Bloody Nora!" as a stronger version.
