Louis is said to be the “legitimate” pretender to the throne, since he is a direct descendant of Louis XIV, according to traditional male line primogeniture (coincidentally, he’s also a descendant of Spanish dictator Francisco Franco and Queen Victoria).
The only other one I see is Prince Jean of France, Duke of Vendôme, who is Jean IV for his royalist followers, amongst these, Action Française.
I'm in America and part of the Kentucky KFC franchise kingdom, or the Kentucky Mandate and Protocol or Portfolio. Here he is on JєωTube, or they say "YouTube" too. Any descendant of Napoleon would be unacceptable to me. Vivre Louisville, Kentucky et les Rois, etc.!
