The eldest child of John Harington, created by James first Baron Harington of Exton, was married to Edward, third Earl of Bedford, in 1594 and was a lady in waiting under Elizabeth. She was one of the group of noble ladies who hastened north on the death of the Queen to welcome, and secure the favour of, James and Anne of Denmark. Her father and mother were granted the tutorship of the young Princess Elizabeth, and she herself was admitted at once as a Lady of the Chamber. Her beauty and talent secured her a distinguished place at Court, and in the years that Donne was a prisoner at Mitcham the Countess was a brilliant figure in more than one of Ben Jonson's masques. 'She was "the crowning rose" in that garland of English beauty which the Spanish ambassador desired Madame Beaumont, the Lady of the French ambassador, to bring with her to an entertainment on the 8th of December, 1603: the three others being Lady Rich, Lady Susan Vere, and Lady Dorothy (Sidney); "and", says the Lady Arabella Stewart, "great cheer they had."' Wiffen, _Historical Memoirs of the House of Russell_, 1833. She figured also in Daniel's Masque, _The Vision of the Twelve Goddesses_, which was published (1604) with an explanatory letter addressed to her. In praising her beauty Donne is thus echoing 'the Catholic voice'. The latest Masque in which she figured was the _Masque of Queens_, 2nd of February, 1609-10. In Court politics the Countess of Bedford seems to have taken some part in the early promotion of Villiers as a rival to the Earl of Somerset; and in 1617 she promoted the marriage of Donne's patron Lord Hay to the youngest daughter of the Earl of Northumberland, against the wish of the bride's father. Match-making seems to have been a hobby of hers, for in 1625 she was an active agent in arranging the match between James, Lord Strange, afterwards Earl of Derby, and Lady Charlotte de la Trémouille, the heroic Countess of Derby who defended Lathom House against the Roundheads. An active and gay life at Court was no proof of the want of a more serious spirit. Lady Bedford was a student and a poet, and the patron of scholars and poets. Sir Thomas Roe presented her with coins and medals; and Drayton, Daniel, Jonson, and Donne were each in turn among the poets whom she befriended and who sang her praises. She loved gardens. One of Donne's finest lyrics is written in the garden of Twickenham Park, which the Countess occupied from 1608 to 1617; and the laying out of the garden at Moore Park in Hertfordshire, where she lived from 1617 to her death in 1627, is commended by her successor in that place, Sir William Temple.
