Mary Stewart, Duchess of Richmond and Duchess of Lennox (1622–1685), formerly Lady Mary Villiers, was the daughter of the George Villiers, 1st Duke of Buckingham and Katherine Manners, 19th Baroness de Ros.
On 8 January 1634, at the age of 12, she married the 15-year-old Charles, Lord Herbert, eldest son of the 4th Earl of Pembroke and 1st Earl of Montgomery, but was widowed in 1635 when her young husband died of smallpox.
Sometime before 1664, Mary married Colonel Thomas Howard (d. 1678): he was a younger brother of Charles Howard, 1st Earl of Carlisle, and is chiefly remembered for his duel in 1662 with Henry Jermyn, 1st Baron Dover.
Maureen E. Mulvihill has built a case for Mary Villiers as the author of the poems published under the pseudonym Ephelia, including Female Poems...by Ephelia (1679).
