Prince Harry and Meghan Markle have made a significant change for their children, Princess Lilibet and Prince Archie, breaking with 64-year-old Royal tradition to give them a new surname.

The youngsters are now known as Sussex instead of Mountbatten-Windsor. This departure was discovered on the couple’s new website, sussex.com, which replaced their old site – Archwell.

The last name Mountbatten-Windsor was originally assigned by Queen Elizabeth II’s advisors in 1960 to her male-line descendants.

This decision has sparked conversation, with some taken aback, leading to claims they’re showing off their connections to royalty.

A Royal expert was surprised to see the kids called Prince and Princess. Archie and Lilibet weren’t princes or princesses at first because they weren’t the monarch’s grandchildren.

But when Charles became King, Archie and Lilibet’s grandad was now the King, so they got to be a prince and princess. At Lilibet’s christening last March, it was announced they would be called Prince and Princess.

Harry and Meghan are in Canada now for the Invictus Games next year. This visit is just after Harry went to the UK because King Charles was sick with cancer.

Harry came from California for a short meeting with Charles, showing he cares despite their past problems. Robert Jobson from the Daily Mail said: “Charles was widely reported to have been touched by the gesture. Perhaps he was.”
