They belong to the most famous family in the world, but life for the Wessexes is surprisingly down to earth. Sophie, 57, has been married to King Charles' youngest brother Prince Edward, 58, since 1999, and they share two children: the Queen's so-called 'favourite' granddaughter Lady Louise Windsor, 18, and James, Viscount Severn, 14.
The couple has remained largely out of the spotlight, but this could change now King Charles is heading up the monarchy - with the two working royals expected to take on a bigger role in the streamlined monarchy.
Sophie and Princess Anne's husband were the only non-blood relatives to be at Balmoral after the monarch's death - with Sophie, 57, previously described as a 'second daughter' to the Queen.
