MacFarlane or Green of "Family Guy" (4)
I believe the answer is:
seth
'macfarlane or green of family guy' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for seth that I've seen before include "Younger brother to Cain and Abel" , "Early human" , "Third son of Adam and Eve" , "One of the first men" , "Cain and Abel's younger brother" .)
