Kith and kin (6,6)
I believe the answer is:
family circle
'kith and kin' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for family circle that I've seen before include "Kith and kin" , "all my relations" , "Collectively" , "Close kin - cheap theatre seats (US)" , "Group composed of one's relatives" .)
