Turn up two hours before noon with daughter (6)
I believe the answer is:
attend
'turn up' is the definition.
(turn up at an event)
'two hours before noon with daughter' is the wordplay.
'two hours before noon' becomes 'at ten' (at ten o'clock).
'with' says to put letters next to each other.
'daughter' becomes 'd' (genealogical abbreviation).
'atten'+'d'='ATTEND'
(Other definitions for attend that I've seen before include "Listen closely" , "Completed" , "minister" , "put in an appearance" , "Be there ? pay attention" .)
