Joan of Kent, first Princess of Wales (1328-1385) was the wife of Edward the Black Prince. Their marriage was a love match; the Plantagenet sons of Edward III had a tendency to defy convention & follow their heart. While Edward & Joan never became King & Queen of England, their surviving son became Richard II. Edward treated his wife affectionately in public & in private; his letter to her seven years after their wedding began, "My dearest and truest sweetheart and beloved companion."
Edward & Richard ~ the 'Princes in the Tower'. These two boys were, in fact Edward V (uncrowned king of England) and his younger brother Richard, the only two surviving sons of the late Edward IV. History (and the Tudors) tell us that the boys were murdered some time after 1483 while resident in the Tower of London, and give the likely culprit as their uncle, King Richard III. Historians continue to debate the issue; I point the finger at Henry VII!
Lady Anne Neville (11 June 1456 – 16 March 1485) was Princess of Wales as the wife of Edward of Westminster and Queen of England as the consort of King Richard III. She held the latter title for less than two years, from 26 June 1483 until her death in March 1485. She had just one son, Edward, whom she outlived.
Berengaria of Navarre c. 1165–1170 – 23 December 1230) was Queen of the English as the wife of King Richard I of England. She was the eldest daughter of King Sancho VI of Navarre and Sancha of Castile. As is the case with many of the medieval queens consort of the Kingdom of England, relatively little is known of her life, altho' we do know that she never entered England during her reign as Queen!
