Overview
Clara Mary Jane Clairmont (27 April 1798 – 19 March 1879), or Claire Clairmont as she was commonly known, was the stepsister of the writer Mary Shelley and the mother of Lord Byron's daughter Allegra. She is thought to be the subject of a poem by Percy Bysshe Shelley.
Early life
Clairmont was born in 1798 in Brislington, near Bristol, England, the second child and only daughter of Mary Jane Vial Clairmont. Throughout her childhood, she was known as Jane. In 2010 the identity of her father was discovered to be John Lethbridge (1746–1815, after 1804 Sir John Lethbridge, 1st Baronet) of Sandhill Park, near Taunton in Somerset. Her mother had identified him as a "Charles Clairmont", adopting the name Clairmont for herself and her children to disguise their illegitimacy. It appears that the father of her first child, Charles, was Charles Abram Marc Gaulis, "a merchant and member of a prominent Swiss family, whom she met in Cadiz".
In December 1801, when Clairmont was three years old, her mother married a neighbour, the writer and philosopher William Godwin. This brought her two stepsisters: Godwin's daughter, later Mary Shelley, only eight months her senior, and his stepdaughter Fanny Imlay, a couple of years older. Both were the daughters of Mary Wollstonecraft, who had died four years before, but whose presence continued to be felt in the household. The new couple soon became the parents of a son, which completed the family.
All five children were influenced by Godwin's radical anarchist philosophical beliefs. Both parents were well-educated and they co-wrote children's primers on Biblical and classical history, and ran a bookshop and publishers known as the Juvenile Library. Godwin encouraged all of his children to read widely and give lectures from early childhood.
