Stuart monarch, somewhat mannered (4)

I believe the answer is:

anne

'stuart monarch' is the definition.
(I've seen this in another clue)

'somewhat mannered' is the wordplay.
'somewhat' indicates a hidden word.
'ANNE' is hidden within 'mannered'.

(Other definitions for anne that I've seen before include "First name of two of Henry VIII's wives" , "Queen's name" , "'---- of Green Gables', novel by Lucy Maud Montgomery" , "Queen seventeen hundred and two to seventeen fourteen" , "Shakespeare's wife's name" .)

I've seen this clue in The Everyman puzzle in The Observer.
