Harry married fan (7)
I believe the answer is:
admirer
'fan' is the definition.
(thesaurus)
'harry married' is the wordplay.
'harry' indicates an anagram (I've seen this in other clues).
'married' with letters rearranged gives 'ADMIRER'.
(Other definitions for admirer that I've seen before include "Supporter or fan" , "One who cherishes, like boy friend" , "Romantic adorer" , "girlfriend?" , "Married to suitor" .)
