William Seymour, 2nd Duke of Somerset was the great-grandson of Edward Seymour, 1st Duke of Somerset (c.1500-1552), the uncle of King Edward VI and Lord Protector of England. Seymour made a secret marriage at Greenwich on 22 June 1610 to Arbella Stuart (d.1615), daughter of Charles Stuart, 1st Earl of Lennox and Elizabeth Cavendish. Arbella was thirteen years his senior, and King James I disapproved of the marriage as the union of two potential Tudor pretenders to the throne, who were respectively fourth and sixth in line, could only be seen as a threat to the ruling dynasty. As a result, William was condemned to life
Algernon Seymour, 15th Duke of Somerset build. After leaving the Regular Army, he spent several years ranching in Western America. On accession to the Dukedom in 1894, he voted often in the House of Lords, although he seldom spoke there. He became president of Dr Barnardo's Homes, a charity which both he and the Duchess had supported for many years. When Somerset died in 1923, he left no son, and his brothers Lord Ernest and Lord Edward had both recently died childless, so his titles and estates were inherited by the nearest heir, his distant cousin Colonel Edward Seymour. The Duke was buried on Brimble Hill
