On my opinion it is correct to call this branch as House of Braganza-Saxe-Coburg and Gotha, that is, through the female line. Because:
1) Robert I Parma died in 1907 and had nothing to do with second marriage children fraud
2) The same is true for Robert first marriage children. Their men had served in the Austrian army during WWI
Although Zita in her statements insisted that they are Bourbon Parma. But these two sisters of Braganza-Saxe-Coburg and Gotha have actively participated in all the intrigues:
1) Maria Theresa of Portugal (24 August 1855 - 12 February 1944), the 3d wife of Karl Ludwig of Austria (30 July 1833 - 19 May 1896). “Maria Theresa managed to obtain considerable influence at the Austrian court when Empress Elisabeth effectively withdrew from the social scene in Vienna after the suicide of her only son, Crown Prince Rudolf, in January 1889. Maria Theresa stood in for the Empress and carried out honours at the Hofburg Imperial Palace with the Emperor until the death of her husband in 1896 when court etiquette ruled she had to go into retirement”
2) Maria Antonia of Portugal (November 28, 1862 - May 14, 1959), 2nd wife of Robert I Parma (9 July 1848 - 16 November 1907). She was the mother of Zita, Sixtus and the other brothers. Also she was a postman in the scam with a peace letter of Karl...)
How many know they both escorted Karl up to Madeira then...
“Sixtus affair” is much broader, that only the well-known peace negotiations in 1916-1917, where Karl was shown as a weak and not reliable ruler.
Zita in circle of her family: Xavier, Sixtus , Maria Antonia. Villa Pianore.
It looks like Braganza-Saxe-Coburg and Gotha family try to get up instead of Osterrich family for almost 100 years.
It is noticeable that also Jesuits are active involved in the case – future warder of Karl “British officer, Lt-Colonel Edward Lisle Strutt was a Catholic educated by Jesuits at Beaumont College, and at Innsbruck and Oxford Universities”.
Remember, Karl did not ask for exile, nor for Madeira.
“…After a difficult few months at Eckartsau, the Imperial Family received aid from an unexpected source. Prince Sixtus had met King George V and appealed to him to help the Habsburgs”.
O! Prince Sixtus ask! It was the selfless aid from an unexpected source on the way to Madeira!)))
“Malta was mooted as a possibility, but was declined by Lord Curzon, and French territory was ruled out due to the possibility of Zita's brothers intriguing on Charles's behalf…”.
Zita's brothers intriguing on Charles's behalf! Very interesting!)
Looks like Zita's brothers intrigue together with King George V and Lord Curzon… on Charles's behalf.
Do not forget Karl was a prisoner in Eckartsau. After he was moved to Switzerland, he became a prisoner of Braganza-Saxe-Coburg and Gotha and their british friends.
Do not forget all this time Karl did not know anything about the fate of his daughter Maria.
Now something about Zita famous speech:
“…Leaving behind their children at Gödöllő, Charles and Zita travelled to the Schönbrunn Palace. By this time ministers had been appointed by the new state of "German-Austria", and by 11 November, together with the emperor's spokesmen, they prepared a manifesto for Charles to sign. Zita, at first glance, mistook it for an abdication and made her famous statement "A sovereign can never abdicate. He can be deposed... All right. That is force. But abdicate — never, never, never! I would rather fall here at your side. Then there would be Otto. And even if all of us here were killed, there would still be other Habsburgs!"
Why Zita was scared so much?) Let's say about later.
Now let's take a look at these her words:
“…I would rather fall here at your side. Then there would be Otto…”
Which Otto did she mean? What line of succession she said about? Karl was standing next to her right now… Apparently these words were not about Karl successor. These words were about other Otto, about the new one, who did not inherit Karl, but succeeded Zita's line.
Zita worried greatly! Because of this we heard so much new now.
Do not forget that on 11/11/1918 and up to Karl death Zita had only titles:
Empress consort of Austria
Queen consort of Hungary and Bohemia
She was not a monarch. She was just the spouse of monarch. And thus she had no heirs.
If it is still interesting, then next time let's talk about how and where “old Otto” (=Maria) disappeared in the late October 1918…
In conclusion, this is concerning “lady in dark” and her family.

The above visas were issued by Aristides de Sousa Mendes in Bordeaux in June 1940, allowing the Imperial Family of Austria to escape the Nazis and effectively saving the life of the Crown Prince Otto von HABSBURG who had been sentenced to death by the Nazis following the Anschluss, the German annexation of Austria.
