Beach god finds girl (6)
I believe the answer is:
sandra
'girl' is the definition.
'beach god' is the wordplay.
'beach' becomes 'sand'.
'god' becomes 'ra' (Ra is an example).
'sand'+'ra'='SANDRA'
'finds' is the link.
(Other definitions for sandra that I've seen before include "So woman" , "woman's name" , "Girl's name" , "girl" .)
