Princes Harry and William remain joint patrons, with their wives, of the Royal Foundation, the primary charitable body for the Cambridges and Sussexes.
Royal commentator Omid Scobie shared Kensington Palace's official announcement, which stated that the royal couples would be splitting up their staffs and bringing in new individuals to their respective private offices and households.
The statement read: "Jason Knauf has been appointed as senior adviser to The Duke and Duchess of Cambridge".
The most common names that appear in both Harry and Meghan's family trees are Mary, John and Elizabeth.
On Thursday, the palace announced Harry and Meghan have officially split royal households from Prince William and Kate Middleton.
The Queen has agreed to the creation of a Household for The Duke and Duchess of Sussex and given permission for it to be based at Buckingham Palace. The two opted to relocate because their new home will be more accommodating for their growing family.
In 2006, she founded the Latham Group and has recently been a managing partner at London PR firm Freuds.
His interview comes on the heels of Kensington Palace's release of a new "strict set of standards" for interacting with the royal family via social media, aiming to create a "safe environment".
The Duke of Sussex now has his own private office, which has been supporting The Duchess since the engagement of Their Royal Highnesses in November 2017.
She is presumed to be a dual British-American citizen and according to a CV found online, she also played a part in Hillary Clinton's 2016 presidential campaign.
It appears that numerous most senior staff, now at Kensington Palace, are staying to work with the Cambridges.
But one thing we know for sure is that Prince Harry will be by her side every step of the way and is even planning on taking a few weeks off himself to spend with baby Sussex once he or she arrives. "The Commonwealth's young people are an incredible asset, and it is vital that we invest in them". House Sussex, then, represents a fresh start as they move out of KP to Frogmore Cottage as their official residence and welcome the birth of their first child.
