Family affair (5)
I believe the answer is:
issue
I believe this clue is a double definition.
'family' is the first definition.
(issue can mean a person's offspring)
'affair' is the second definition.
(thesaurus)
(Other definitions for issue that I've seen before include "Important topic for debate" , "important point" , "Circulate, distribute or equip with" , "Outflow or point of concern" , "Matter, point" .)
