誰が Cecilia Underwood, 1st Duchess of Inverness と結婚しましたか？

Cecilia Underwood, Duchess of Inverness (née Gore and formerly Buggin; c. 1789 – 1 August 1873) was the second wife of Prince Augustus Frederick, Duke of Sussex (sixth son of King George III). Despite marrying, like the Prince's first marriage, their union was in contravention of the Royal Marriages Act 1772 and as such was considered legally void. Consequently, she could not be styled either as the Duchess of Sussex nor a Princess. She was created Duchess of Inverness, in her own right, by Queen Victoria, on 10 April 1840.
