Their firstborn son, Prince George’s name has special meaning. His full name, George Alexander Louis, was chosen with love and a nod to history.

Alexander is believed to have been picked by the couple to honor the Queen, whose middle name is Alexandra. Louis is likely a tribute to Prince Philip, whose grandfather was Prince Louis Alexander of Battenberg. It also has great meaning to William’s own father, Prince Charles, whose uncle and mentor, Earl Louis Mountbatten, was assassinated by the IRA in 1979.

Will and Kate represented the baby’s grandfather, Prince Charles, by going for the female version of his name. And they included Princess Diana, which was a popular choice with friends and admirers of her legacy. They also added the ultimate nod to great-granny and reigning monarch Queen Elizabeth II.
