Guesses, please

We know the Black family motto is "toujours pur".
What is the Malfoy's motto? Any suggestions? I would expect something French, and something along the lines of "le plus et le mieux" was the first that came into my mind, but
a) My French is not all that good and
b) I am not really creative when it comes to tag lines, as my lack of creativity when looking for story titles shows.


For those not familiar with the Harry Potter books, what would you use as the family motto of a supercilious, old, rich family?
