Galloway gal (4)
I believe the answer is:
lass
'galloway gal' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lass that I've seen before include "Sweet resident of Richmond Hill?" , "Young woman, girl" , "Damsel" , "Girl (of Richmond Hill?)" , "Sweetheart" .)
