One of the more interesting things that's expected to happen after the queen's death is the status of her younger son, Prince Edward. Unlike most royal sons, Edward did not receive a ducal title upon marriage, instead becoming the Earl of Wessex. Reportedly, that's because he's expected to become the Duke of Edinburgh once his father, Prince Philip, has died.
It's a bit complicated, though. Prince Philip's titles pass to his eldest son — Charles, who can't be Duke of Edinburgh and king, so the title will "revert to the Crown." So Charles will then have to "remake" the title to pass it to Edward, who will then become a duke and his wife, Sophie, a duchess. Still with us?
