Relative from Spain visiting somewhere in France (5)
I believe the answer is:
niece
'relative' is the definition.
(niece is a kind of relative)
'spain visiting somewhere in france' is the wordplay.
'spain' becomes 'e' (abbreviation for Espana).
'visiting' indicates putting letters inside.
'somewhere in france' becomes 'nice' (French city).
'e' put within 'nice' is 'NIECE'.
'from' is the link.
(Other definitions for niece that I've seen before include "A sibling's child" , "Criminal" , "Brother or sister's daughter" , "Family relation" , "Son's cousin" .)
