1610: William Seymour secretly married Arbella Stuart at Greenwich. News of the marriage caused great consternation at court – the pair were both descendants of the Tudor line, so there was the danger of a rival dynasty to that of James I. The pair were separated and imprisoned for marrying without royal permission. Both escaped from captivity and fled for the continent. Seymour managed to reach Ostend but the ship carrying Arbella was overtaken and she was taken back to the Tower, where she remained until her death in 1615.
