Buckingham Palace said William is now His Royal Highness The Duke of Cambridge, and that Miss Catherine Middleton is now Her Royal Highness The Duchess of Cambridge.
There's more: The palace statement said William was also named the Earl of Strathearn and Baron Carrickfergus. Middleton took those titles when she said "I will," becoming Countess of Strathearn and Baroness Carrickfergus.
Strathearn ties William and Middleton to Scotland, where the pair met and fell in love. Baron Carrickfergus is a little-used title which refers to one of the oldest towns in Northern Ireland.
