For example, Kate Middleton and Prince William, Duke and Duchess of Cambridge, have opted to use their royal title of Cambridge as their children's surnames instead of Mountbatten-Windsor (probably in order to blend in a tiny bit more into normal society).
The Duke and Duchess of Sussex announced on Thursday have appointed Hillary Clinton's former campaign advisor to head up their communications team, as they are set to totally cut ties from Kensington Palace.
In a statement, the Palace said the changes for the Sussexes "will ensure that permanent support arrangements for The Duke and Duchess' work are in place as they start their family and move to their official residence at Frogmore Cottage".
The Duke and Duchess of Sussex are to bring in their own team to shape their future work in the Royal Family, as they build a new Sussex brand on a global platform.
Embracing one of her new royal roles roles - the ACU, which fosters greater links between students and higher education institutions across the Commonwealth of 53 nations - she has written a supportive open letter to welcome a new strategy.
The news also comes as the couple is preparing their move to Frogmore Cottage.
The announcement of the new household is a natural development in the life of senior royals and facilitates their need to have their own staff and aides around them as they pursue their public goals. They will also be appointing a new communications staff which will become a part of the Buckingham Palace communications staff.
"Meghan has very strong views on what she is interested in and that may be what Harry shares, but not what William and Kate share", she continued.
Given this rift, and the many questions bound to arise from the household split, it makes sense that Sara Latham was tapped to handle PR for the new Sussex household.
Now, all we can do is wait and see.
