Girl in part of France (8)
I believe the answer is:
lorraine
I believe this clue is a double definition.
'girl' is the first definition.
(woman's name)
'part of france' is the second definition.
(I know that France is a is part of of Lorraine)
'in' acts as a link.
(Other definitions for lorraine that I've seen before include "French region bordering Germany" , "Region of north-eastern France" , "French sister province of Alsace" , "Area of France after which a style of cross is named" , "French region, cross" .)
