Hi Arturo ! My brother who is a historian tells me that the matter is not so clear-cut. It seems that Felipe V's descendance could claim the throne of France if there was one to be claimed(the treaty apparently stipulated that the King of Spain could not be also King of France but another man of his branch / family could).
I will not got into the deepest arguments regarding this...however, in France when Chambord died in 1883 - monarchists did not look to Spain for leadership, they looked to the Orléans. In France when Charles X was King, the line of succession went from his eldest son, the Duc d'angouleme, to his grandson, the Duc de Bordeaux (also known as Comte de Chambord), to his cousin, the Duc d'Orléans. Just before dying in 1883, Chambord left writings in which he argued that even though he had renounced the throne for moral issues, once he was dead, the Count of Paris (eldest grandson of Louis Phiiippe), would have t deal with political issues surrounding the thrnoe and an eventual restoration. Chambord himself never looked at the Bourbons of Spain, the Two sicilies and Parma as his political heirs. Apres moi, les Orléans!
