On 30th August 1548 the Queen Dowager, Catherine Parr gave birth to a daughter at Sudeley Castle, the home she shared with her fourth husband, Thomas Seymour.
Catherine Parr spent the final three months of her pregnancy at Sudeley Castle preparing for the birth of her first child. Catherine ensured that she was surrounded by her closest friends including her chaplain, Miles Coverdale, her almoner, John Parkhurst as well as her ladies from when she was Queen.
Shortly before her confinement was due to begin Catherine decorated the nursery, it was situated looking over the gardens and chapel. It was decorated in crimson and gold velvet and taffeta. Beside the cradle was a bed with crimson curtains as well as a separate bed designated for the new child’s nurse.
The daughter was named Mary, after the Queen Dowager’s eldest step daughter and future Queen. Just six days after her birth Catherine died of puerperal fever and was laid to rest within the grounds of Sudeley Castle. Mary was then brought up with her father as her main guardian, Seymour took Mary to London and placed her with her aunt and uncle, the Duke and Duchess of Somerset, who had just had their own child. Mary remained here until Seymour was executed for treason just seven months later leaving Mary an orphan.
Due to an appeal made to William Cecil by Katherine Brandon, Duchess of Suffolk we know that she was appointed Mary’s guardian after Seymour’s death, it appears that she resented being given the young child to care for and referred to her as ‘the Queens daughter’ in her letter. Katherine Brandon was appealing to Cecil to gain his help with talking to the Lord Protector, the Duke of Somerset regarding the upkeep of Mary’s household. The household was expensive to maintain as Mary was still the child of a Queen and therefore needed a lady governess, rocker and her own servants despite her young age. However, in January 1550 an act of Parliament was passed that allowed Mary to inherit Seymour’s properties and therefore a regular income.
Records show no other mention of Mary after this date, she was just 16 months old, she never stood forward to claim her inheritance and so it is believed that she died as an infant. It is likely that she is buried near Grimsthorpe in the estate owned by Katherine Brandon.
