Mary Montagu, Countess of Cardigan
Mary Montagu, Duchess of Montagu, known as Countess of Cardigan between 1730 and 1749, was the wife of George Brudenell, 4th Earl of Cardigan. She was the daughter of John Montagu, 2nd Duke of Montagu, on whose death in 1749 her husband inherited the family estates and took the surname "Montagu". Her mother was Lady Mary Churchill, daughter of John Churchill, 1st Duke of Marlborough. In 1766, her husband the earl was made a duke, reviving the titles that had become extinct as a result of his father-in-law's death without a male heir.
Lady Mary married the earl on 7 July 1730 at St Giles-in-the-Fields. They had two children:
Other children died in infancy.
The duchess died at the age of about 63, and was buried at St Edmund's Church, Warkton, Northamptonshire. Her memorial was sculpted by Peter Mathias van Gelder to a design by Robert Adam, and was completed in 1781.Titles and styles
