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!
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."
