Wrong about him (3)

I believe the answer is:

ron

'him' is the definition.
(short for Ronald)

'wrong about' is the wordplay.
'about' indicates a hidden word (the clue goes around or about the answer).
'RON' can be found hidden inside 'wrong'.

(Other definitions for ron that I've seen before include "L. - Hubbard, US sci-fi writer" , "Short man's name" , "Man" , "Shortened man's name" , "--- Weasley, Harry Potter pal" .)

I've seen this clue in The Mirror.
