Born in 1519, Mary Howard was the daughter of Thomas Howard, third Duke of Norfolk. Her mother, Elizabeth, was the daughter of the disgraced Edward Stafford, Duke of Buckingham. Mary was highly educated, and spent the majority of her childhood at the family residences in Norfolk. As she entered her teenage years, Mary participated in ceremonies at court, including that of her kinswoman Anne Boleyn’s elevation to the marquisate of Pembroke in September 1532. It is likely that Mary also attended Anne’s coronation the following summer, and she carried the chrism at Princess Elizabeth’s christening in September. She seems to have shared the queen’s reformist sympathies and was rebuked by her brother for her love of reading the scriptures.
