When Archie was born in May 2019, Harry’s name was listed as "His Royal Highness Henry Charles Albert David Duke of Sussex" and Meghan’s was listed as "Rachel Meghan Her Royal Highness The Duchess of Sussex." Their occupations, which are not required on California birth certificates, were listed as “Prince” and “Princess of the United Kingdom.”
Since Archie’s birth, Harry and Megan have stepped down as senior royals and left the U.K.
When Prince Charles becomes king, Archie and Lili will automatically become a prince and a princess as grandchildren of the reigning monarch.
Harry and Meghan announced Lili’s arrival on their Archewell website, writing, "On June 4th, we were blessed with the arrival of our daughter, Lili. She is more than we could have ever imagined, and we remain grateful for the love and prayers we've felt from across the globe. Thank you for your continued kindness and support during this very special time for our family."
