But when Augustus married again when he held the Duke of Sussex title, his second wife was also not eligible to be known as the Duchess of Sussex either.
Augustus married Lady Cecilia Gore in 1831, a marriage which also did not get the approval of the monarch.
Therefore Cecilia was never considered Augustus’ legitimate wife, and therefore could not attend court or use the title of Duchess of Sussex.
After Augustus’ death, the Duke of Sussex title became extinct.
