Old kings and queens from Stroud (6)
I believe the answer is:
tudors
'old kings and queens' is the definition.
I can't judge whether this defines the answer.
'from stroud' is the wordplay.
'from' is an anagram indicator (the anagram comes from the same letters).
'stroud' is an anagram of 'TUDORS'.
Can you help me to learn more?
(Other definitions for tudors that I've seen before include "English monarchs from Henry VII to Elizabeth I" , "Royal family" , "Members of a house" , "Members of English royal line" , "Royalty" .)
