On 9 September, Charles III announced the creation of William as Prince of Wales.
William has since been known as "His Royal Highness The Prince of Wales", except in Scotland where he has been styled as "His Royal Highness The Duke of Rothesay", since the accession of his father.When William becomes king, his wife, Kate, will assume the courtesy title of "Queen Consort." There are three types of queen in the British monarchical system: A Queen Regnant, who reigns in her own right; a Queen Consort, who is queen because her husband is king; and a Queen Dowager, who is the widow of a king.The Earl descended from King Edward III through both his parents.
Prince Charles and the late Princess Diana both descend from Sir William Gascoigne and his wife Lady Margaret.
“This makes William and Kate fourteenth cousins once removed through his mother and fifteenth cousins through his father.
