I believe the answer is:

ohara

(Other definitions for ohara that I've seen before include "Scarlett ..... is famous heroine of fiction (1'4)" , "Maureen ..., star of 'The Quiet Man' (1'4)" , "Scarlett ....., heroine of ''Gone with the Wind'' (1'4)" , "film heroine" , "See 1 Across" .)

I've seen this clue in the Universal.
