Lady Arbella Stuart (also Arabella, or Stewart; 1575 – 25 September 1615) was an English noblewoman who was considered a possible successor to Elizabeth I. During the reign of James VI and I (her first cousin), she married William Seymour, 2nd Duke of Somerset, another claimant to the English throne, in secret. King James imprisoned Seymour and placed her under house arrest. When she and her husband tried to escape England, she was captured and imprisoned in the Tower of London, where she died at age 39.
