Green Gables heroine (4)
I believe the answer is:
anne
'green gables heroine' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for anne that I've seen before include "Prince Charles's sister" , "- - Hathaway, wife of Shakespeare" , "Boleyn or Hathaway, say" , "23's sister" , "Shakespeare's wife's name" .)
