Paxton House in Berwickshire was once owned by Ninian Home, the owner of two sugar plantations on the island of Grenada. The Wedderburn Papers, part of the house archives, contain some 2,000 documents relating to the Grenada properties between the 1760s and the 1840s. In 2007, the Paxton Trust began a project to digitise and increase access to all the documents relating to Grenada (including correspondence between Grenada and Paxton, plus documents relating to the plantations and their enslaved workers). A booklet and exhibition was also organised, and links were made with a youth group based in Acton, London, most members of which are of Grenadian descent. The Wedderburn Papers are held at the National Archives of Scotland.

The Lascelles Slavery Archive was a collaborative project between the Borthwick Institute for Archives and Harewood House Trust to conserve, preserve and make available records relating to slavery from the archives of the Lascelles family of Harewood House, Yorkshire. The project deals with a new discovery of papers relating to the family's fortune based on its estates in the West Indies. Key documents providing evidence for the acquisition of the family's wealth, once thought lost, were found in poor condition during an inventory of Harewood House. The Lascelles Slavery Archive is available through the Borthwick's searchrooms as an online resource, and represents an important section of the larger archive of the Lascelles family held by West Yorkshire Archive Service.
