Just adding to the "Fannygate" discussion.

fanny (n.)

"buttocks," 1920, American English, from earlier British meaning "vulva" (1879), perhaps from the name of John Cleland's heroine in the scandalous novel "Fanny Hill or Memoirs of a Woman of Pleasure" (1748). The fem. proper name is a diminutive of Frances.


Here we see an early British researcher documenting the word "fanny" for the Encyclopedia Britannica.
