A little over a week ago, Shloss Nymphenburg made the sad announcement that Duke Franz of Bavaria (whom Jacobites and legitimists consider to be our rightful king, and publically acclaim as Francis II) had been diagnosed with cancer. His Royal Highness is receiving treatment, and the prognosis is said to be good. While we wish him a speedy recovery and a restoration to good health, we must concede that the attention of royal watchers the world over has shifted this morning to the usurping House of Windsor (or Mountbatten-Windsor, as Prince Charles looks likely to rename it when he ascends to the throne), and the announcement by that other palace that Their Royal Highnesses the Duke and Duchess of Cambridge are expecting their first child.
