The royals are known for their commitment to traditions and protocol, especially when it comes to naming new family members. It is said that all names are even required to pass through Queen Elizabeth II before being officially given.

This trend has continued with the names William Arthur Philip Louis and Henry Charles Albert David, more commonly known as Prince William and Prince Harry, but those weren't the first choices of Prince Charles.

According to The Fresh Toast, the Prince and Princess of Wales had been contemplating other names before finally settling on the ones we know today. During interviews that biographer Andrew Morton conducted for his 1992 book "Diana: Her True Story," the late Princess revealed that while she did come up with their official first names, Charles' initial choices were dismissed.

When Diana was asked who chose Harry's name, she responded, "I did."

"I chose William and Harry, but Charles did the rest," Diana said, adding, "He wanted Albert and Arthur, and I said no. Too old!"

However, it remains unclear which brother would have been given which name had Charles gotten his way.
