What if the Jacobites had attacked London?

 

The present Queen is descended from the Stuarts, as indeed was George I.

 

The answer would depend very much on what children the pretender had, other than the ones he had anyway. As it is the promiscuous Charles left no legitimate male child (and only an illegitimate female one) and his brother Henry was a bishop. The Stuart line died out in 1807 when Henry died, leaving (as far as I can track it) the succession going to .... George III (except he would have been George I).

 

IMO If he had taken the royals in London and effectively held them for ransom in the seat of British power, there would have been a negotiated settlement. weighted heavily in his favour.

 

Norman: William I, conquered the place
Plantagenet (Angevin): Henry II, inherited from his mother, who married the Count of Anjou
Lancaster: Henry IV, took the throne from Richard II via rebellion, and used the family name of his father, John of Gaunt, Duke of Lancaster
York: Edward IV, also took the throne via rebellion against Henry VI, and took the family name from his father, the Duke of York.
Tudor: Henry VII, another rebellion this time against Richard III. Henry's claim was through his mother, who was married to Edmund Tudor.
Stuart: James I & VI, inheriting via his mother Mary of Scots back up to his great-grandmother, Henry VIII's sister, who married James IV (Stuart) of Scotland. His father was another Stuart.)
Hanover: George I, whose claim was through his grandmother, daughter of James I.
Saxe-Coburg: Edward VII, whose mother was Queen Victoria, who married Albert of Saxe-Coburg.
Windsor: Name adopted by George V (of Saxe-Coburg) during WWI.

As you can see, houses change either when the throne is taken by force, or when succession is through the female line. Or, as with Henry Tudor, both.

 

 

Which would in fact be Mountbatten, since that is the (adopted) family name of her husband. It has absolutely nothing to do with who Philip's ancestors were.

 

Otherwise, as I pointed out before, every monarch since William would be House of Normandy.

 

It's dead simple really. The name of the house is simply the family surname, which follows the normal English rules for family names. Legitimate children are named after their father. (Illegitimate children don't succeed, unless they are conquerors )

 

The only difference is that a woman marrying changes her surname, whereas a Queen keeps her house. So Mary I was Tudor, not a Habsburg, though her chidren would have been Habsburg if she had any. Mary II was Stuart not Orange, though her children would have been Orange. Anne was also Stuart, though her children would have been whatever the family name of the contemporary Danish house was.
