Overview
Augusta Maria Leigh (née Byron; 26 January 1783 – 12 October 1851) was the only daughter of John "Mad Jack" Byron, the poet Lord Byron's father, by his first wife, Amelia, née Darcy (Lady Conyers in her own right and the divorced wife of Francis, Marquis of Carmarthen).
Early life
Augusta's mother died soon after her birth. Her grandmother, Lady Holderness, raised Augusta for a few years, but died when Augusta was still a young girl, and the child divided her time among relatives and friends.
Marriage
Augusta later married her cousin, Lt. Colonel George Leigh (1771–1850), son of General Charles Leigh (1748–1815) and his wife, Frances Byron, her paternal aunt. The couple had seven children: Georgiana Augusta, Augusta Charlotte, George Henry, Elizabeth Medora, Frederick George, Amelia Marianne, and Henry Francis. Richard Temple-Nugent-Brydges-Chandos-Grenville, 1st Duke of Buckingham and Chandos, noted the wedding with disdain in his diary: "Poor Augusta Leigh marries today! Poor thing! I pity her connecting herself with such a Family and such a fool! However, she has nobody to blame but herself." The marriage turned out unhappily because he fell into dissolution and gambled away all his money. In the end, he left his wife and children nothing but debts.
Lord Byron
Augusta's half-brother, George Lord Byron, did not meet her until he went to Harrow School, and even then only very rarely. From 1804 onward, however, she wrote to him regularly and became his confidante, especially in his quarrels with his mother. Their correspondence ceased for two years after Byron had gone abroad, and was not resumed until she sent him a letter expressing her sympathy on the death of his mother, Catherine in 1811.
