"Duke of Bourbon and Burgundy" ??

[Sam Marroy]

I was recently reading the Wikipedia pages for a couple weddings within the royal family from the 1950s/60s (specifically Princess Alexandra and Angus Ogilvy) and in the list of guests was "The Duke of Bourbon and Burgundy". When clicked, the link directed to Alfonso de Borbon, Duke of Cadiz in the peerage of Spain and Duke of Anjou as Legitimist claimant to the French throne. 

Now, at the time of those weddings, he had not been created Duke of Cadiz or assumed the title Duke of Anjou, but I can't find anything that indicates he was ever known as either the Duke of Bourbon or the Duke of Burgundy, and when searched on Google, the only results are from the pages related to those weddings. Was there a political or diplomatic reason why he would have been referred to by those seemingly invented titles, ie not wanting to refer to him in a way that would seem to express preference for his claim to the French throne over the Count of Paris and the descendents of Napoleon? That's the only real explanation I can come up with seeing as it seems, based on my research that British royal weddings are the only circumstances under which he was referred to as Bourbon & Burgundy

The attendance of this person (Duke of Bourbon, Cadiz, or otherwise) was added on 1 January 2025 by User PrincedeConti - they seem to contribute to articles about continental royalty.  No reference was given for the addition, though this doesn't mean the Duke didn't attend.

I have limited knowledge to contribute, but he does appear to have been created Duke of Bourbon in 1950, albeit in pretense.

Ah, good work - I should have thought to check the source of that edit but a 60 year old wedding isn't something I thought folks would be actively editing to shoehorn in references to their favorite pretender, haha. 

He was a pretty high profile figure, not only the Legitimist claimant to the French throne but also rumored to have been considered by Franco as a potential King of Spain before he decided on Juan Carlos, but with French monarchist movements decidedly fringe groups at this stage in history, there's not a whole lot of information available online on the various titles of pretense used by claimants and their family members, at least not in English.
