Daughter of Elizabeth II (4)
I believe the answer is:
anne
'daughter of elizabeth ii' 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 "Girl's name" , "First queen of Great Britain and Ireland" , "Queen seventeen hundred and two to seventeen fourteen" , "Queen in 1702-14" , "Stuart queen" .)
