Sarah Ferguson and Prince Andrew steered clear from "royal names" and chose Beatrice and Eugenie.
Carolyn Harris, author of Raising Royalty: 1000 Years of Royal Parenting, told Vogue Australia, “The further down the line of succession, the more likely you are to have a more unique or untraditional name."
“We see, from the diversity of names among the Queen’s descendants, that the Queen does seem willing to allow the descendants to choose their own names.”
However, Harry and Meghan must still follow one rule when it comes to their new baby.
The couple must not announce the name of their child's name until Queen Elizabeth and the rest of the Royal Family have been told.
According to royal commentator Victoria Arbiter the reasons for this is so they can celebrate their new arrival in private and check the name is suitable.
“Royals, however, also have to consider the great responsibility in naming a new member of the family and I expect they want to be a hundred per cent certain of their choice before announcing the name and sealing the baby’s place in history,” Arbiter told Town and Country.
