Who is the Great Catholic Monarch? 
An Interview with Xavier Reyes-Ayral
(Qui est le Grand Monarque Catholique ? Entretien avec Xavier Reyes-Ayral)
No one knows if he will be French!
Hi. I've done some research on this as I've known about it for a while. I have lived in France. As he says in the video it is definitely true that Our Lady told Maximin Giraud and Melanie Calvert that Louis XVII was still alive. For some reason the Bishop and the Vatican kept it secret (as they have the third secret of Fatima) as it is politically explosive! The Great Monarch will be a direct descendant of Louis XVI and Marie Antionette.
Maximin visited the Comte de Chambord with a message from Our Lady. The Holy Virgin told the Comte via Maximin that he must not accept the Throne of France as Louis XVII was still alive.
The Comte de Chambord's Secretary made a note of the Conversation.
Apparently Marie Julie Jahenny also referred to the survival of Louis XVII.
Melanie Calvert at some juncture told her Confessor the Abbe Combe that the "Naundorf"family descended from Louis XVII. It's written in the Abbe's book "
"Journal de l'abbé Combe. Dernières années de Soeur Marie de la Croix, bergère de la Salette"
