Oscar winner Bancroft (4)
I believe the answer is:
anne
'oscar winner bancroft' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for anne that I've seen before include "--- Elliot, later Wentworth (J. Austen)" , "British monarch, d. 1714" , "She married Shakespeare" , "Name of queen or princess" , "- of Green Gables (children's classic)" .)
