Why didn't Prince William and Princess Kate attend Sam Bransons wedding?

No, because he is still His Royal Highness the Prince of Wales, as well as Duke of Cambridge Earl of Strathearn Baron Carrickfergus I think he was given a title for each area of the United Kingdom so that no-one felt left out. His full title is actually now: His Royal Highness Prince William Arthur Philip Louis, Duke of Cambridge, Earl of Strathearn, Baron Carrickfergus, Royal Knight Companion of the Most Noble Order of the Garter, Master of Arts.

Prince William is still a prince. He just holds this new title (along with a number of others) in addition to the title he was born with. It's quite common for the Queen to grant titles as gifts, and it's important because if give Kate (who is a commoner) more standing.

On her marriage she became Princess William of Wales, but now she is legitimately Duchess of Cambridge.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
