Royal Baby Prince Louis's Name Has an Important Meaning

Kate Middleton and Prince William welcomed a healthy baby boy Monday morning, and after making us wait a long five days, Kensington Palace finally revealed that his name is Prince Louis Arthur Charles.

Louis

Meaning: renowned warrior, according to Nameberry.com

Origin: French, German

The name Louis holds a special meaning to the family—now, all three males share the name. It is one of the names given to Prince William and Prince George at birth. What a sweet father-son bond. It's likely a nod to Prince Philip's favorite uncle, Lord Louis Mountbatten.

Prince Louis actually shares two names with his dad. The Duke of Cambridge and his youngest son both have Arthur and Louis in their names—Will's full name is William Arthur Philip Louis.

Arthur

Meaning: bear, according to Nameberry.com

Origin: Celtic

Louis shares his second name, Arthur, with both his father and grandfather. The Prince of Wales' full name is Prince Charles Philip Arthur George. It appears that the name could be a nod to the mythical King Arthur who was one of England's most well-known monarchs in medieval times.

Charles

Meaning: free man, according to Nameberry.com

Origin: French, German

Prince Louis' third name, Charles, is an obvious nod to Will's father the Prince of Wales, who will become King one day.

Kate and Will have a knack for keeping names in the family. Each one given to their children has a specific meaning. Here's the meaning behind Prince George's and Princess Charlotte's full names.

Prince George Alexander Louis

When it came to naming their first son, Kate and Will went with George, which is the name of Queen Elizabeth's father, King George VI, who is Prince William's great grandfather. George's second name, Alexander, pays tribute to the Queen whose full name is Elizabeth Alexandra Mary. At the time, Kate said the name Alexandra was at the top of her list if the baby was girl.

George's third name, Louis, comes from his father's name—Prince William Arthur Philip Louis. It's likely that the name was first given to William to commemorate the Duke of Edinburgh's uncle, Lord Louis Mountbatten.

Princess Charlotte Elizabeth Diana

Princess Charlotte's first name has a dual meaning—it's a female version of the name Charles, who is William's father, and it happens to be Kate's sister, Pippa Middleton's middle name (how convenient!). You can likely guess where Charlotte's second and third names comes from. Elizabeth is definitely a nod to the Queen and the Queen Mother, while Diana was given to her to pay homage to Prince William's late mother who tragically passed away in a car accident.
