Celebrity family (4)
I believe the answer is:
name
I believe this is a double definition.
'celebrity' is the first definition.
(thesaurus)
'family' is the second definition.
(name is a kind of family)
(Other definitions for name that I've seen before include "Handle" , "Good reputation; specify; christen" , "Famous person; reputation" , "By which one is known" , "By which a person is known" .)
