The Duffield Memorial is a gravesite monument located in the churchyard of the Church of St Mary in Great Baddow, England. Designed by Herbert Maryon and installed in 1912, it originally memorialised Marianna Duffield and William Ward Duffield, who died in 1910 and 1912, respectively. A second plaque was added to commemorate their son, William Bartleet Duffield, who died in 1918. The memorial covers the grave, and comprises edging and a vertical cross. It is designed in the Art Nouveau style and is made of riveted sections of copper alloy sheet metal. The edging follows the rectangular perimeter of the plot, and features short pillars at each corner. The cross is a Celtic wheel cross decorated in relief with leaflike motifs. A curved shaft connects it to the foot, which, like the four-sided base upon which it is mounted, has curved and splayed sides. The plaques memorialising the Duffields are riveted to the base; a medallion was once riveted to the centre of the cross, but is now lost. Newspapers at the time termed the memorial "very fine" and "quite unique" for the area, and in 2022 it was designated a Grade II Listed Building. The list entry terms the memorial both "an unusual example of churchyard memorial design", and "an unusual example of Art Nouveau design in metal work, well detailed and combined with a conventional form of churchyard memorial, a Celtic wheeled cross". Background The Duffields The Duffields were a prominent family in Chelmsford, having settled in Great Baddow by the time of Henry VIII. William Ward Duffield was born on 25 November 1820 to James Duffield, a farmer. He went on to become a successful solicitor, founding the Chelmsford firm Duffield and Son, and the London firm Duffield, Bruty and Co. He also held many public roles, including as clerk to the Chelmsford Board of Governors, clerk to the Justices at Chelmsford, registrar of the Chelmsford County Court and Bankruptcy Court, and governor of the King Edward VI School. His private positions included as director and chairman of entities including the Reliance Life Assurance Company, the London Board of the Norwich Union, the Chelmsford and Braintree Gas Companies, and the Chelmsford and Blackwater Navigation Company. Duffield married Marianna Bartleet on 10 March 1860. The couple had three surviving children: William Bartleet Duffield (1861–1918), Arthur Stewart Duffield (1867–1930), and Florence Marion Duffield.
