Overview
Elizabeth Medora Leigh (15 April 1814 – 28 August 1849) was the third daughter of Augusta Leigh. It is widely speculated that she was fathered by her mother's half-brother Lord Byron, which is supported by comments from his widow, even though her mother's husband Colonel George Leigh was her official father.
Birth
She was born as the middle child of seven children. Three days after her birth, Byron visited Augusta and the baby. He later wrote to a friend, Lady Melbourne: "Oh! but it is 'worth while' – I can't tell you why – and it is not an Ape and if it is – that must be my fault."
The child's middle name was taken from the heroine of Byron's poem The Corsair. In the family, she was known as Elizabeth or "Libby", but she also later used the name Medora.
In 1816, the scandal over his separation from his wife Annabella, rumours surrounding his relationship with Augusta, and mounting debts forced Byron to leave England. He never returned.
Early life
Augusta's husband, George, never questioned the paternity of Medora, and she grew up among her brothers and sisters unaware that she might be the first of Byron's three daughters. As a young teenager, she was seduced by her brother-in-law, Henry Trevanion, unhappily married to her older sister Georgiana. She had accompanied the couple when they took up residence in Canterbury in a house belonging to their aunt, Lady Byron. When neighbours reported the scandalous appearance of an apparently pregnant unwed teenager to Lady Byron, she arranged for the trio to travel to France, where the child was born and placed for adoption. Medora returned home, but the relationship continued and she became pregnant again. The three departed for Bath to stay in a house of one of Henry's relatives in an attempt to hide the second pregnancy from Medora's father, Colonel Leigh. The Colonel was eventually informed, and after travelling to Bath with an attorney removed her from the Trevanions and sent Medora to an establishment in London, to give birth in secrecy. After she miscarried, Henry arranged for her escape and in 1831 the couple eloped to France.
Marriage and France
Henry Trevanion and Medora set up in an ancient, tumble-down chateau near Morlaix in France, living under the surname Aubin. By 1833 Henry and Medora were living in Brittany, at the Breton Carhaix.
