What happened to Katherine Parr’s daughter, Mary Seymour, after her mother’s death?
Katherine Parr, the final wife of the deceased King Henry VIII, died in 1548, leaving a baby daughter called Mary, just a few days old. What is known about what happened to Mary Seymour? Historian Linda Porter explains more…
Following Katherine Parr's death a matter of days after Mary's birth, the newborn's father, Thomas Seymour, placed Mary in the household of his brother, Edward Seymour the Duke of Somerset. But the brothers’ relationship deteriorated and as Thomas faced death for treason, he appointed the Duchess of Suffolk, Katherine’s close friend, as Mary’s guardian.
The Duchess of Suffolk’s main estate was at Grimsthorpe in Lincolnshire and Mary moved there with her little retinue. Her guardian resented the cost of looking after Mary and petitioned William Cecil, then in Somerset’s household, for additional funds to support her. These were granted in autumn 1549, and in January 1550 an act of parliament restored Mary’s title to her father’s remaining property.
There was, however, very little left. The Privy Council’s grant to Mary was not renewed in September 1550 and she never claimed any part of her father’s estate, leading to the conclusion that she died around the time of her second birthday.
There is a story that Mary survived, cared for by the Aglionbys (a northern family who had once been clients of the Parrs), and married a courtier in the service of Anne of Denmark, queen of James VI and I. In the absence of documentary proof, it seems far likelier that this tragic orphan died very young.
