Daughter of man worried about followers (6)
I believe the answer is:
fandom
'followers' is the definition.
(fandom is a kind of followers)
'daughter of man worried' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'worried' indicates an anagram (worry can mean to interfere with or disturb).
'd'+'of'+'man'='dofman'
'dofman' anagrammed gives 'FANDOM'.
'about' is the link.
(Other definitions for fandom that I've seen before include "Devotees, collectively" , "enthusiasm" , "Supporters generally" , "devotion" , "body of supporters" .)
