The Trust has become the guardian of the Marriott family archive, much of which has survived intact at the Hall, a happy consequence of the long term ownership of one family.

The earliest document, recording a land transaction in Cotesbach, dates from the time of Henry VI, a Plantagenet (1422-1461) and as such is a gem of local history.  The collection covers the 15th to the 20th century and includes deeds and papers relating to the Estate, substantial family correspondence and papers, and important groups of sermons and religious papers (of particular value for the study of Anglican sensibilities and practice in the late 18th and early 19th century.

• The archive will be on permanent loan to the CET and is to be housed in the Coach House which is to be specially converted for archive storage to national standards, with public viewing space.
• In addition there are small collections of artefacts, such as a toy collection (late 18th century to the present) which will be made accessible for the CET to use as educational resource material.
