The Devonshire Collection Archives hold the majority of the extant historic personal papers of the Dukes and Duchesses of Devonshire. In addition the archives hold many papers for other family members and associated individuals.

The catalogues to the family papers have been broadly arranged into three groups:

Selected Cavendish and Devonshire Family Collection catalogues are currently available online via links to PDFs in the relevant sections below. We are also now contributing detailed catalogues to the Archives Hub and The National Archives' Discovery databases; links to these are also found below where relevant. If you wish to see the catalogues of any other collections mentioned in this guide, please contact the archives team by email.

This guide is not comprehensive and does not include partly or fully uncatalogued collections, or material still closed to researchers. There are many nuances in using the catalogues in the Devonshire Archives, as such it is always worth asking the archivist if you have any doubts. See Note on the arrangement of the family papers for further information on how the collections came to be arranged as they are.

You can also download the family papers guidance notes detailed on this page.

Note on the arrangement of family papers

The archive at Chatsworth has a complicated history, as such the process for finding all existing papers for one particular person is not limited to searching one catalogue. Researchers may find it useful to have an understanding of how the archives came to be catalogued, and how they came to be arranged as they are.

Family Correspondence


  • CS1: First Correspondence Series
  • CS2: Second Correspondence Series
  • CS4: 4th Duke’s Correspondence Group
  • CS5: 5th Duke’s Correspondence Group
  • CS6: 6th Duke’s Correspondence Group
  • CS8: 8th Duke’s Correspondence Group

It was not until the 1920s that a concerted effort was undertaken to comprehensively catalogue the family, social and political correspondence that had accumulated through the centuries at Chatsworth.

During 1925 and 1926, all letters dated before and including 1839 were catalogued as First Correspondence Series (CS1). As well as the direct ancestors of the Cavendish line, CS1 included correspondence for persons who had married into the family and whose papers came to be kept at Chatsworth. Such families include the Earls of Burlington, and material for their ancestors, the Savile and Finch families. In its initial form, the First Correspondence Series comprised c.10,000 letters.

Subsequently, during 1926 and 1927, all letters (then known to exist) that were dated between 1840 and 1908 were catalogued as Second Correspondence Series (CS2).

Although these two collections still exist, they have been heavily altered across the last ninety years. Most pertinently, in various stages from the 1970s through the 2000s the correspondence of the 4th, 5th and 6th Dukes of Devonshire, their families and associates were extracted to form, respectively, the 4th Duke's Group (CS4); the 5th Duke’s Group (CS5) and the 6th Duke’s group (CS6).

With these ducal papers extracted, the number of letters remaining in First Correspondence Series is now approximately 2800, the vast majority of the papers dating to before 1755, the date when the 4th Duke came into his title.

The Second Correspondence Series has been less altered, but all letters of the 8th Duke of Devonshire, including those before he became Duke, have been re-catalogued as the 8th Duke’s Correspondence group (CS8) and removed from the Second Correspondence Series.

Devonshire Family Collections


DF1 to DF37

A further complication that can be added to the above is that when the First and Second Correspondence Series collections were compiled they, by definition, did not include other family papers such as diaries, scrapbooks, photos, keepsakes and legal papers. Furthermore, correspondence of family members then still living were not then considered archival.

This extra material was left uncatalogued until 2014, when an 18 month project to gather and list any material not previously catalogued created the Devonshire Family collections groups of material that predominately focus on family members from the 19th and 20th centuries.

Notes on searching the collections

The above complications can make searching for all relevant material on a given member of the Cavendish family difficult. For example you can find personal material for the 6th Duke in the 5th Duke’s Group (CS5), the 6th Duke’s Group (CS6), Joseph Paxton’s Correspondence (P), the Second Correspondence Series (CS2) and in the relevant Devonshire Family Collection (which is DF4) - a total of 5 separate collections!

It helps when searching for material to bear in mind:

  1. If the person died before 1755 their correspondence is likely to be in the First Correspondence Series. Check also to see if they have a named collection (A DF number)
  2. From 1755 until 1840, most correspondence is filed under the relevant ducal group and so it is helpful to know the years of the ducal reigns. For example, the 6th Duke’s correspondence as Marquis of Hartington (i.e. before 1811), can be found in the 5th Duke’s group. Ducal periods and associated correspondence groups:
    • 4th Duke (CS4) 1755-1764
    • 5th Duke (CS5) 1764-1811
    • 6th Duke (CS6) 1811-1858 NB 6th Duke correspondence after 1840 can be found in Second Correspondence Series (CS2).
    • 8th Duke (CS8) 1841-1908 NB unlike the other ducal series, this catalogue includes material from immediate family members to Spencer Cavendish before he became Duke in 1892
  3. For correspondence between 1840 and 1908 material can be found in a number of places, notably CS8 and the Second Correspondence Series catalogue. Do also check if there was any extra material gathered together to form the Devonshire Family Collections (DF) - the majority of which date from the mid-19th century onward.
