His other daughter, previously 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 previously' is the wordplay.
'other' is an anagram indicator.
'daughter' becomes 'd' (genealogical abbreviation).
'previously' means one lot of letters go next to another.
'his' is an anagram of 'ish'.
'ish' put after 'd' is 'DISH'.
(Other definitions for dish that I've seen before include "bit of pottery?" , "Person who's smashing" , "Menu item - plate" , "Attractive person" , "Peach" .)
