According to Prince Harry's memoir, Camilla and Charles wanted Kate Middleton to change her name.

To avoid confusion with the existing royal cyphers, they suggested she spell it "Katherine" with a K.

Harry recalls this incident and wonders what happened to their suggestion.

He looks at his brother, Prince William, to see if he is taken aback by this news.

Prince Harry's expression demonstrates that Prince Charles supported them financially out of duty rather than generosity.

The royal family already has cyphers that begin with a C and end with a crown, which could lead to confusion with another C-named royal.

To avoid this confusion, it was suggested that Kate Middleton's name be changed.

It's unclear whether Kate Middleton ever seriously considered changing her name's spelling.

This demonstrates how King Charles and Camilla have an impact on royal family decisions.
