About Mary Seymour

Mary Seymour was the only daughter of Thomas Seymour, 1st Baron Seymour of Sudeley, and the dowager queen, Catherine Parr, widow of Henry VIII. Although Catherine was married four times, Mary was her only child, born at her father's country seat, Sudeley Castle in Gloucestershire. Complications from Mary's birth would claim the life of her mother on 5 September 1548, and her father was executed less than a year later for treason against her cousin Edward VI.
