Concise News learned that the couple announced the names on their official Instagram account.
According to them, they showed Queen Elizabeth II, Harry’s 93-year-old grandmother, her eighth great-grandchild earlier on Wednesday.
The queen’s husband, Prince Philip, and Meghan’s mother, Doria Ragland, were “also present for this special occasion,” they added, posting a black-and-white photograph of the group smiling at Archie as Meghan held him.
“It’s magic, it’s pretty amazing. I have the two best guys in the world so I’m really happy,” Meghan told reporters earlier as Harry held Archie inside the royal Windsor Castle, West of London.
“He has the sweetest temperament, he’s really calm,” Meghan added.
“I wonder who he gets that from?” Harry joked.
