Who is Prince William named after?

The Duke of Cambridge’s full name is William Arthur Philip Louis. The prince’s late mother chose his first name.  In Andrew Morton’s 1992 book, Diana: Her StoryPrincess Diana said, “I chose William and Harry, but Charles did the rest. He wanted Albert and Arthur, and I said no. Too old!” The Princess of Wales was inspired by William of Gloucester who was ninth in line for the British throne when he died tragically in a plane crash in 1972.

The prince’s middle names are more self-explanatory. Philip pays homage to the prince’s grandfather, Prince Philip, Duke of Edinburgh while Arthur and Louis are both royal family names that he shares with his father, Prince Charles Philip Arthur George. and sons,  Prince George Alexander Louis, and Prince Louis Arthur Charles.
