Englishwoman who became the Countess of Lennox after secretly marrying Charles Stuart, 1st Earl of Lennox, in 1574.
She was born in Derbyshire, England to Bess of Hardwick and Sir William Cavendish.
She died at the age of twenty-six, just six years after her husband had succumbed to tuberculosis.
She had one daughter, Arbella Stuart, with the 1st Earl of Lennox. Arbella followed in her mother's footsteps by marrying an heir to the throne (William Seymour, 2nd Duke of Somerset) without securing royal approval for the nuptials.
