Frederica Murray, Countess of Mansfield

Frederica Murray, Countess of Mansfield (born Frederica Markham; 1774 – 29 April 1860), formerly Frederica Markham, was the wife of David William Murray, 3rd Earl of Mansfield.

Frederica was one of the seven daughters of William Markham, Archbishop of York, and his wife, the former Sarah Goddard. Another, George, was Dean of York.

As her father was a very close friend of David Murray, 2nd Earl of Mansfield, Frederica might possibly be named after the first wife of the 2nd Earl who was Countess Henrietta Frederica.

In 1796 her husband succeeded his father, David Murray, 2nd Earl of Mansfield, as Earl of Mansfield; he inherited Kenwood House in Camden, London. The family also had homes in Scotland and Ireland. The following year, on 16 September 1797, he married Frederica.

They had nine children:

Lady Frederica Louisa Murray (1800–1823), who married James Hamilton Stanhope and had children Lady Elizabeth Anne Murray (1803–1880), who became Lady of the Bedchamber to Princess Mary, Duchess of Gloucester and Edinburgh William David (1806–1898), who succeeded as 4th Earl of Mansfield, married Louisa Ellison, and had children Lady Georgina Catherine Murray (1807–1871) Lady Cecilia Sarah Murray (1814–1830) Lady Emily Murray (1816–1902), who married Francis Seymour, later 5th Marquess of Hertford, and had children

The countess's father, the Archbishop of York, died in 1807. The countess is thought to have been responsible for extensive works carried out on Kenwood House in the period 1813–1816, which necessitated a doubling of staff.
