Town and Country report that the name has a special meaning for the local people.
“The reason we chose that was mostly because Archie means the same thing that Ntsika does," Jessica Dewhurst, the executive director of The Justice Desk, told the publication.
“So Archie means strength, it means bravery and the South African equivalent of that is Ntsika.
“When you get your traditional name it’s what you will look up to be.
“So when they give you a name it’s your wish for you and your future.”
While royal watchers are used to keeping track of Duchess Meghan's wardrobe choices, it was baby Archie who had fans excited after photos emerged of the tot arriving in South Africa.
Archie was bundled up in navy and a familiar-looking knitted cream bobble hat as the Duchess of Sussex carried him down the steps of the aeroplane.
The Daily Mail published photos of the arrival, and royal watchers noted that Archie's hat looked similar to one worn by the Duke as a baby in 1985. Too cute!
