Middleton and William’s third child may be royal, but technically, he was born as a commonerAccording to Historian Marlene Koenig, “It sounds complicated, but in the UK, the only people who are not commoners are the Sovereign and peers of the realm, [people with titles like] Duke, Marquess, Earl, Viscount, and Baron.”

That means even Prince Harry is technically a commoner — until he earned the “duke” title by marrying Meghan Markle.

Royal baby No. 3 was actually born on a significant holiday for his country. England celebrates St. George’s Day on Apr. 23, which is “the feast day of St. George, the patron saint of England,” according to People.

St. George was named “the protector of the royal family and the patron saint of the country during the Middle Ages.” He was believed to have been a soldier who was tortured as he refused to deny his Christian faith.

At an Anzac Day service, Prince Williams told the press, “Sleeping’s going reasonably well so far, so he’s behaving himself which is good.”  However, many people noticed William nodding off during the service, so he may just be putting on a brave face as he and Kate adjust to another newborn.

Another major royal event occurred shortly after Louis’ birth: his uncle Prince Harry’s wedding to new royal. Meghan Markle. Though some wondered if the baby would attend, the royals chose to keep the young child at home and away from the chaos of the big day.

However, his two older siblings played an important part in the wedding. Prince George was a pageboy, while Princess Charlotte served as one of Markle’s young bridesmaids.

William and Kate’s biggest inspiration for the name Louis comes from Lord Louis Mountbatten, Prince Philip’s uncle. Fulfilling a paternal role for young Philip, the British naval officer ensured Philip got a good education and even introduced him to Queen Elizabeth.

Mountbatten also mentored Prince Charles, who said, “I admire him almost more than anybody else I know.” In 1979, Mountbatten died in a boating accident. He was 79 years old.
