Ones named in wills (5)
I believe the answer is:
heirs
'ones named in wills' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for heirs that I've seen before include "Inheritors" , "They get rank, property etc from others, perhaps their parents" , "Successors" , "They inherit property or rank" .)
