Recently, a document was made public online that confirms this fact.
According to the leaked birth certificate of Lilibeth Diana Mountbatten-Windsor, the former Duchess is listed as Rachel Meghan Markle under “Mother”.
Note that when the couple’s firstborn, Archie Harrison, was born, Meghan was signed as “Rachel Meghan, Her Royal Highness the Duchess of Sussex.”
Prince Harry, however, was not affected by these changes. In the column “Father”, he is still listed as “The Duke of Sussex, HRH”.
Recall that Harry and Meghan’s daughter was born in Santa Barbara Cottage Hospital on June 4, 2021.
