William Seymour, 2nd Duke of Somerset, (1588 – 24 October 1660) was an English nobleman and Royalist commander in the English Civil War.

Frances Seymour, Duchess of Somerset (née Devereux; 30 September 1599 – 24 April 1674) was an English noblewoman who lived during the reigns of Elizabeth I, James I, Charles I and Charles II. Her father was Robert Devereux, 2nd Earl of Essex, Elizabeth I's favourite who was executed for treason in 1601. She was the second wife of William Seymour, 2nd Duke of Somerset, and the mother of his seven children.

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.
