Cecil family, Marquesses of Exeter

On the death of the 2nd Earl of Exeter without male issue in 1640, some Lincolnshire property (Stamford etc.) passed to his youngest daughter Anne, wife of the 2nd Baron Grey of Groby, who was created Earl of Stamford in 1628. But the estates centred on Burghley House were consolidated by later Earls of Exeter and the Earl of Stamford's estate at Stamford was reacquired in the mid 18th century. The 10th Earl of Exeter was created Marquess of Exeter in 1801. A large estate near Crowland (Lincolnshire) was purchased by the 2nd Marquess of Exeter c.1829 but sold after his death in 1867. The Yorkshire and Bedfordshire estates were sold in the late 18th and early 19th centuries, and the London property (in the Strand) c.1850.

Estates in 1883: 15,625 acres in Northamptonshire; 8,998 acres in Rutland; 3,095 acres in Lincolnshire; and 553 acres in Leicestershire; worth a total of £49,044 a year.
