Girl from Hampton-in-Arden (4)
I believe the answer is:
nina
'girl' is the definition.
'from hampton-in-arden' is the wordplay.
'from' says the answer is hidden in the clue.
'NINA' is hidden within 'hampton in arden'.
(Other definitions for nina that I've seen before include "- Simone, US singer" , "- - Simone, 1933-2003, singer" , "Al Hirschfeld's 'hidden' daughter" , "Girl" , "One of Columbus's ships in 1492; girl's name" .)
