High Quality Content by WIKIPEDIA articles! The Lady Caroline Lamb (13 November 1785 – 26 January 1828) was a British aristocrat and novelist, best known for her affair with Lord Byron in 1812. Her husband was the 2nd Viscount Melbourne, the Prime Minister. However, she was never the Viscountess Melbourne because she died before Melbourne succeeded to the peerage; hence, she is known to history as Lady Caroline Lamb.
