Harry, Meghan will be Duke and Duchess of Sussex

Prince Harry and his bride Meghan Markle will be known as the Duke and Duchess of Sussex after their wedding on Saturday, Buckingham Palace announced just hours before the ceremony.
"The Queen has today been pleased to confer a dukedom on Prince Henry of Wales. His titles will be Duke of Sussex, Earl of Dumbarton and Baron Kilkeel," it said in a statement.
"Prince Harry thus becomes His Royal Highness The Duke of Sussex, and Ms. Meghan Markle on marriage will become Her Royal Highness The Duchess of Sussex."

A dukedom is the highest rank in the British peerage. It is traditional to give royal sons titles reflecting the three historic realms -- England, Scotland and Ireland -- that made up the United Kingdom.
Hours before his wedding in 2011, Prince William, Harry's brother and best man, became the Duke of Cambridge, Earl of Strathearn and Baron Carrickfergus.
