Kate Middleton goes through many different titles, and the Duchess of Cambridge is the most common among them.
While the Duchess is an eminent part of the royal family, not many know what her name will be when her husband, Prince William, ascends the throne as king.
As the royal tradition dictates, once William succeeds in becoming King, Kate will automatically become Queen.
This is different in that she will not be known as the Queen of England in the same way as now Queen Elizabeth II.
This is because she is not part of the direct line of succession and will become a monarch through marriage.
It is widely believed that Kate will then be called Queen Catherine when her husband is king.
The official website of Buckingham Palace states: “Unless otherwise decided, the Queen’s ally is crowned with a generous, similar but simpler ceremony.”
The same thing happened to Prince Philip when Queen Elizabeth became the sole ruler of England in 1952.
The Duke of Edinburgh made him an ally.
Things will be different with Charles and Camilla, however, because during their marriage Clarence House said that she would take the title of companion of the princess when Charles becomes king.
