Allegra Byron

Clara Allegra Byron (12 January 1817 – 20 April 1822) was the illegitimate daughter of the poet George Gordon, Lord Byron, and Claire Clairmont. Born in Bath, England, she was initially named Alba, meaning "dawn", or "white", by her mother. At first she lived with her mother, her mother's stepsister, Mary Shelley, and Mary's husband Percy Bysshe Shelley. When she was fifteen months old, she was turned over to Byron, who changed her name to Allegra.

Byron placed her with foster families and later in a Roman Catholic convent, where she died at the age of five of typhus or malaria.
