Mary Howard was born in 1519 into one of the most powerful families in England. Her father, Thomas Howard, the Earl of Surrey, had led English troops to a decisive victory at the Battle of Flodden, crushing the Scots and securing his place in the king’s good graces. Her grandparents were dukes and duchesses, and her family tree included Anne Boleyn, Jane Seymour, and Catherine Howard—three of Henry VIII’s wives. The Howards were known for scheming, falling in and out of royal favor, never hesitating to wield their influence.
But Mary’s childhood, though privileged, was far from peaceful. Her parents’ marriage crumbled, and when her father took a mistress and moved her into their home, tensions boiled over. Still, Mary grew up intelligent, beautiful, and capable—qualities her family would use without mercy. In 1525, Henry VIII elevated his illegitimate son, Henry FitzRoy, to the Dukedom of Richmond and Somerset.
When Cardinal Wolsey fell from grace, Mary’s father seized the opportunity to take the young duke under his guidance. Seeing an opening, the king, with a nudge from Anne Boleyn, suggested that Mary should marry his son. The families quickly agreed, and in November 1533, thirteen-year-old Mary wed the fourteen-year-old Henry FitzRoy. She was now a Duchess, but not a wife in the truest sense: the king, fearing that bedroom activity at such a young age was unhealthy, forbade them from consummating their marriage.
For three years, Mary’s prospects gleamed. Henry VIII had no legitimate male heir, and her young husband was seen as the most likely candidate for the throne. She likely dreamed of being crowned Queen of England. Then her husband contracted tuberculosis and died on July 23rd, 1536, just over a month after his seventeenth birthday.
Now the king made a devastating move. Since the marriage had never been consummated, he declared, it wasn’t valid. Mary was stripped of the lands she would have inherited as a widow. She was left with her title, her place at court, and little else.
Mary settled into a quiet widowhood. She was jovial and well-liked, and she grew close to her late husband’s cousin, Margaret Douglas. Together, they curated the Devonshire manuscript, a collection of Tudor poetry featuring their own work alongside pieces by court poets. For a time, she seemed content to live out her days creatively.
Then political scandal erupted. In 1542, her first cousin, Catherine Howard, Henry VIII’s fifth wife, was accused of infidelity. The king imprisoned her—and her entire extended family. Mary FitzRoy ended up in the Tower of London with the rest of the Howards.
Stuck in prison, Mary’s father could think of only one way out: marry his daughter off again. He petitioned the king for Mary to marry Thomas Seymour, the brother of Henry’s third wife, Jane. Surprisingly, the king approved. Mary’s family breathed a collective sigh of relief, believing their treasured daughter would steer them back into royal favor.
But Mary had no interest in Thomas Seymour—and she made that clear. She strongly objected, and the marriage never took place. She wasn’t alone in her resistance. Her brother Henry, the Earl of Surrey, also opposed the match—but for his own reasons.
He was scheming independently of their father to win back the king’s favor. And like their father, he was not hesitant to use his sister as a pawn. Surrey suggested Mary seduce Henry VIII himself. She was outraged, and she didn’t hide it.
The two stubborn siblings had a bitter falling out and stopped speaking entirely. That rift would have devastating consequences. Soon after, Mary’s father and brother were put on trial for treason. Then Mary made a move that shook everyone.
She testified against her own family members. Whether driven by self-preservation or genuinely held beliefs, her dramatic testimony helped seal the fates of two of the most powerful Howards in England. Her brother was executed on January 19th, 1547. Her father was scheduled to follow nine days later—but in the early hours of January 28th, Henry VIII died, throwing the kingdom into chaos.
The new king, Edward VI, never bothered to carry out the execution of a man charged with treason against his predecessor. Mary’s father was instead imprisoned in the Tower of London for the rest of the young king’s reign. Though she never had children of her own, Mary took charge of her brother’s five children after his execution. She proved shrewdly aware of the shifting religious currents at court: though raised a devout Catholic by her father, England’s premier Roman Catholic nobleman, she was far more sympathetic to reformist ideas than the rest of her family.
She hired Protestant martyrologist John Fox to tutor her wards, securing their place in the new royal order. Mary never remarried. She largely faded into the background after Henry VIII’s death, becoming essentially a faceless courtier wielding no meaningful power again. She was probably relieved to do so.
In January 1556, Queen Mary I took the throne and began reversing many of her father’s reforms. Mary FitzRoy wasn’t worried—she was the queen’s sister-in-law. She died on December 7th, 1557, at the age of 37 or 38, possibly after a difficult bout of flu.
She left behind a legacy of quiet independence and a ruthless, decisive intelligence thather family—and the kingdom—never saw coming.
