Clue: Successor to Ximenes got up and embraced one little girl or another from Cornwall (7)
Answer: DEMELZA
Explanation: Definition: another from Cornwall
An envelope ('embraced') of MEL (diminutive of Melanie, 'little girl') in DEZA, a reversal ('got up' in a down light) of AZED ('successor to Ximenes' as setter of the barred crossword in the *Observer*). 'Another' in the definition would seem to indicate another girl, presumably the character from *Poldark*, rather than the Cornish village.
