Ever since Prince Harry and Meghan Markle's May 19 wedding, baby buzz has been in full-swing for the couple.
Both the Duke and Duchess of Sussex have made it no secret they wish to start a family, but should there be any new royal arrivals there will be one notable difference between them and cousins George, Charlotte and Louis.
Harry and Meghan's children will likely have different surnames.
Despite all of Prince Philip and Queen Elizabeth's children, grandchildren and great-grandchildren all historically sharing the surname Mountbatten-Windsor, it is most likely Harry and Meghan's children with adopt the surname Sussex.
When William and Harry were at school, they were known as William and Harry Wales — a consequence of their dad being Prince Charles of Wales.
Similarly, George, Charlotte and Louis are known as the Cambridges, referring to their parents titles as the Duke and Duchess of Cambridge.
It’s thought the decision was made to help the royal children blend into their school environment, while also neatly tying in with their parents’ titles.
