I would suggest that there are very few European Royal Families who have lost their thrones a few hundred years ago, most were during the last century or so. The Hapsburgs still live in Austria, and, I seem to remember that there is a Hapsburg in the current Austrian government. There are two pretenders to the French throne, the Bourbon, Louis, Duke of Anjou lives in Madrid, the Orleans, Henri, Comte de Paris lives in Paris. There is an interesting list here: http://en.wikipedia.org/wiki/List_of_current_pretenders#Europe

There was a news article just this past week about a Romanian princess who was sentenced for running a cock-fighting ring.
