According to Thomas Woodcock of the Garter King of Arms, Harry and Markle’s daughter would be automatically be a “Lady” given that her father is a duke. The baby could be technically named Lady alongside the name her parents have chosen, then Mountbatten-Windsor.
Woodcock also clarified that the baby’s older sibling, Archie Harrison Mountbatten-Windsor, who was born in May 2019, had an automatic aristocratic title as well. The Duke and Duchess of Sussex’s first-born son is actually the Earl of Dumbarton but Woodcock said Harry and Markle turned the title down and instead chose their son’s name to be styled as Master Archie Harrison Mountbatten-Windsor.
The Sussex child’s aristocratic title is similar to Princess Diana, Harry’s mother. Before she married Prince Charles, she was known as Lady Diana Spencer as she was from an aristocratic family.
Prince Harry and Markle’s second child will be the eighth in line to the British throne upon her birth, before her brother and father. Her arrival will push down the line of succession beginning with Prince Andrew’s family, who will drop to the ninth (Andrew), 10th (Princess Beatrice), 11th (Princess Eugenie) and 12th (Eugenie’s son, August Philip), respectively.
Meanwhile, Mechanical explained in her interview with Oprah Winfrey that she wanted Archie to have a royal title as a prince so he could gain royal protection, as shouldered by the taxpayers. However, she said that this decision was not made for her son and implied that the royal family had discussions about her son’s skin color before he was born.
The Duchess of Sussex said it upset her that the first colored member of the British royal family will not be titled in the same way as the other grandchildren, referring to Prince George, Princess Charlotte, and Prince Louis, the children of Prince William and Kate Middleton. However, Archie was not yet going to be titled as a prince because of a 100-year-old ruling made by King George V, Queen Elizabeth’s grandfather, that the Princes of Wales’ first-born son’s children would have royal titles. In this situation, this refers to Prince Charles’ grandchildren from Prince William’s line of the family.
Prince Charles, however, could grant the royal title to Archie when he is the king by issuing an order just like King George V. Markle implied that this was not part of the plan for Archie or her future children with Prince Harry.
