Duchess teacup

I have 6 of these Duchess teacups but have been unsuccessful finding anything else from this set. Does anyone know what this particular design is called? I can find plenty of “Marie” pieces but my teacups are a soft green and it seems impossible to find any information about them.

 

Good morning and welcome to the board.

We're going to need photos of the item and of any marks.
