Amelia Osborne, Marchioness of Carmarthen and de jure 12th Baroness Darcy de Knayth and 9th Baroness Conyers, as well as 5th Countess of Mértola (née Darcy; 12 October 1754 – 27 January 1784), was a British peer and a Portuguese countess.

Life

She was the only surviving child of Robert Darcy, 4th Earl of Holderness, and his wife, Mary Doublet. On 29 November 1773, she married Francis Osborne, Marquess of Carmarthen, and they had three children:
Lord and Lady Carmarthen divorced in May 1779. A month later, she married John "Mad Jack" Byron (father of the poet, Lord Byron) and they had one daughter, Augusta Leigh. A year earlier, Amelia had inherited the right to her father's baronies of Darcy de Knayth and Conyers (although this wasn't confirmed until 1798, long after her death), and she also inherited the Portuguese countship of Mértola from him. On her own death in 1784, the titles were inherited by her eldest son, George.
