[7] Chiefly through the favour of George Villiers, Duke of Buckingham Cary was appointed to succeed Sir Oliver St John, as Lord Deputy of Ireland.

She published a translation of French Cardinal Jacques Davy Duperron's reply to the attack on his works by King James, but the book was ordered burned.
