This quizz is great but the coat of arm used for Normandy is the one of the country, not the one of the family. You should have used the one with three lions created by Richard Lion-heart that inspired the coat of arm of Normandy.
The House of Normandy actually became extinct before the age of heraldry (and before Richard the Lionheart), so I chose to use the later arms of the land (the duchy), just like Wikipedia does (https://en.wikipedia.org/wiki/House_of_Normandy).
