His other daughter started as an attractive person (4)
I believe the answer is:
dish
'an attractive person' is the definition.
(dish can mean an attractive person)
'his other daughter started' is the wordplay.
'other' indicates anagramming the letters.
'daughter' becomes 'd' (genealogical abbreviation).
'started' is a charade indicator (letters next to each other).
'his' with letters rearranged gives 'ish'.
'ish' after 'd' is 'DISH'.
'as' is the link.
(Other definitions for dish that I've seen before include "Shallow bowl" , "Person who's smashing" , "Bowl-shaped aerial; utterly destroy (colloq.)" , "Attractive person" , "receiver to >screw up" .)
