Gloucestershire town where Tudors settled (6)
I believe the answer is:
stroud
'gloucestershire town' is the definition.
(I've seen this before)
'tudors settled' is the wordplay.
'settled' indicates an anagram.
'tudors' with letters rearranged gives 'STROUD'.
'where' acts as a link.
(Other definitions for stroud that I've seen before include "Gloucestershire town" , "Cotswold town" , "English town" .)
