Radclyffe/Derwentwater Papers Contents A collection of original manuscripts and transcripts relating to the earls of Derwentwater and the Radclyffe family. The material itself, mostly letters with some legal papers, is chiefly of a personal nature. It includes information relating to the finances of the Radclyffe family and the management of the Derwentwater estate. Some letters make reference to the Catholic faith of various members of the family, although there is little on the wider political situation, with the exception of a series of transcripts relating to the 1715 Jacobite Rising copied from the Clavering MSS held at Durham University Library Special Collections, as well as some printed items on legal acts relating to Catholic lands. 1563-1718
