The year 2016 has been a momentous one for H.M. Queen Elizabeth II. On 6th February we celebrated her accession (at the age of 25y,10m), and on 21st April we joined celebrations as she became the first European monarch to reach the age of 90. On 9th September she had reigned for 23,226 days, 16 hours and 23 minutes and on waking, she set a new record by passing the longevity set by the reign of Queen Victoria. She had already reigned longer than Henry III (56y), George III (59y) and King Louis XIV of France (72y). I notified Buckingham Palace of our contributions to the celebrations. Her Majesty very graciously dictated a letter, mentioning in particular the participation by Daniel, William and Susanne.
