Scottish family (4)
I believe the answer is:
clan
'scottish family' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for clan that I've seen before include "Kinship group" , "Scottish tribe" , "Group of families with common ancestor" , "One from Benghazi" , "Tribe or collection of families under a cheiftain" .)
