Thank you for posting this link. The historical facts seem to be correct - but just one thing: the site is a "Jacobite"-site, meaning the owners support the claim that the Crown of England and Scotland should have been inherited through the line of king James VI. of Scotland/James I. of England's granddaughter Henriette Marie, duchess of Orleans instead of his daughter Elizabeth Stuart (whose descendants are the current Royal family). Jacobites ignore that Henriette Marie renounced her claims to the thrones of England and Scotland for herself and her children on her marriage to the French king's brother while her aunt's rights to the succession were restored to her by Henriette Marie's brother king Charles II. of England and Scotland when Elizabeth and her son Rupert (who became a loyal, highly decorated and successful admiral for childless king Charles II.) came back to live in London. So for the Jacobites Crown Prince Rupprecht (Rupert) of Bavaria was king Rupert of Great Britain with Crown Princess Antonia of Bavaria, his wife as his queen. Thus the way to present the persons with titles they actually did not held.
Of all the children of princess Elizabeth Stuart only her daughter, electress Sophia of Hanover, left issue with unrenounced inheritance rights - through which the current Royal family is descended
