Of a man who lives at Crouch End (3)

I believe the answer is:
his
'of a man' is the definition.
The definition suggests a singular noun but the answer is a plural noun.
'lives at crouch end' is the wordplay.
'lives' becomes 'is' ('be' can be a synonym of 'live').
'at' is a charade indicator (letters next to each other) (I've seen this in other clues).
'end' says to take the final letters.
The last letter of 'crouch' is 'h'.
'is' put after 'h' is 'HIS'.
'who' acts as a link.
Can you help me to learn more?
(Other definitions for his that I've seen before include "that chap's" , "That man's" , "Belonging to the male" , "Belonging to that man" , "It belongs to him" .)
