Title: Official and personal papers of the Nassau d'Auverquerque family, c1577-1753
Description:

The documents include official papers of Count Henry de Nassau d'Auverquerque as Master of the Horse to William III, and a small number of items in connection with his position as Field Marshall of the Dutch forces and as Captain of the King's Guard; some accounts of his household and that of his wife Frances Madame d'Auverquerque after his death; estate papers and accounts relating to Madame d'Auverquerque's administration of the affairs of her grandson the Earl of Bath; household and other accounts of the Earl of Grantham; and a large number of official and personal papers of Count William Maurice de Nassau, a military commander and governor of Sluys and Dutch Flanders, including financial papers, household accounts, voluminous correspondence and documents concerning Dutch military and civil administration.

 

The majority of the documents, except those concerning the Earl of Bath's estates, are in Dutch, but a considerable number are in French. The description of each item or bundle includes mention of the language or languages in which it is written when this includes a language other than English. Dates should be assumed to be New Style in the case of those documents written on the Continent, and Old Style in the case of those written in England.

 

Many of the papers, in particular the bundles of Count William Maurice's correspondence, bear traces of one or more series of original numbers. These have been noted where found, although it is apparent that some of the bundles to which they relate have been broken up or otherwise tampered with.

Custodial history:

The Nassau d'Auverquerque archives form part of the Cowper collection of documents formerly at Panshanger, a country house near Hertford demolished in 1953. These papers have been treated independently of the main group of Panshanger documents as they form virtually a separate archive, which passed to George Augustus 3rd Earl Cowper as the eventual heir to both the Dutch and English branches of the Nassau d'Auverquerque family. Earl Cowper was the sole male grandchild of Henry de Nassau d'Auverquerque, Earl of Grantham, who some eighteen months before his death in December 1754 had inherited the fortune of his brother Count William Maurice, whose own children had pre-deceased him. It appears that the documents were sent to Florence when Earl Cowper was in residence there, and that they were brought back to Cole Green House, which was then the main residence of the Earls Cowper, on his death in 1789.
