Good-natured family departs (4)
I believe the answer is:
Here is my best explanation:
'good-natured' is the definition.
('kind' is associated in meaning with 'good-natured')
'family departs' is the subsidiary indication.
'family' becomes 'kin' ('kin' can be a synonym of 'family').
'departs' becomes 'd' (common abbreviation e.g. train timetables).
(Other definitions for kind that I've seen before include "Character, nature", "Friendly, generous and considerate", "Sort of compassionate", "Gentle and friendly", "Sympathetic", "Gracious", "Considerate; sort", "Friendly - type", "Taking a plunge" and "Type; helpful".)
