Margaret de Holand was a notable figure in 15th-century England, born around 1430. She was the daughter of Thomas de Holand, the 2nd Earl of Kent, and Alice Fitzalan. Margaret became a prominent member of the English nobility through her marriage to John Beaufort, the 1st Duke of Somerset, which connected her to the powerful Beaufort family. Margaret's lineage linked her to significant royal bloodlines, as the Beauforts were descendants of John of Gaunt, a son of Edward III. Throughout her life, she played a role in the complex political landscape of the time, particularly during the Wars of the Roses, which shaped England's history.
