On 30th August 1548, Catherine Parr, Queen Dowager, and wife of Thomas Seymour, Baron Seymour of Sudeley, gave birth to her first child at Sudeley Castle in Gloucestershire. The baby was a little girl and the couple named her Mary after Catherine’s stepdaughter and friend, Mary Tudor (the future Mary I).
Unfortunately, little Mary Seymour was orphaned before her first birthday. Her mother died just six days after her birth and her father was executed on 20th March 1549. You can read more about this and what happened to Mary in my article from last year – click here.
