Could this be Madame Buréau?

"The Old White China, of which I have often spoken, is by far the best of them all for a white bed; Clara Sylvain is the next best white, and Madame Bureau the third best white. These three would make a bed, planted in the order I have them here, Madame on the outside, Clara next, and the old one in the centre.
