1466:

Elizabeth of York, Queen of England

Elizabeth was the daughter of Edward IV, wife of Henry VII, and mother of Henry VIII. Shortly after her father's death, the invalidity of her father's marriage to her mother, Elizabeth Woodville, was revealed, and she and her brothers Edward and Richard were declared illegitimate and barred from succession to the throne.

After Henry Tudor defeated Richard III at the Battle of Bosworth and took the crown, he had the legislation that decreed Elizabeth illegitimate overturned. His marriage to the legitimate daughter of a king bolstered his claim to the throne. At this time Elizabeth's brothers were most likely already dead, but who killed them is still a mystery.

Elizabeth had nine children and died in childbirth on February 11th, 1503.

Pope St. Gregory II

Gregory entered church service young and achieved significant responsibilities early in his career, including the posts of subdeacon, papal librarian, and treasurer, before becoming pope in 715. He supported the Eastern Roman Empire, but when Emperor Leo III began his campaign against icons, Gregory opposed him and the controversy over iconoclasm began.
