Stick with ashen daughter (4)
I believe the answer is:
wand
'stick' is the definition.
(a wand is a small stick)
'with ashen daughter' is the wordplay.
'with' says to put letters next to each other.
'ashen' becomes 'wan' (very pale).
'daughter' becomes 'd' (genealogical abbreviation).
'wan' next to 'd' is 'WAND'.
(Other definitions for wand that I've seen before include "Magician's rod" , "Wizard's rod" , "Slender, supple stick" , "Conjuror's stick" , "Rod of magician or water-diviner" .)
