The Crutchley Muniments comprise the muniments of the Coke family of Longford in Derbyshire and Holkham in Norfolk. The family's estates lay principally in Derbyshire, Lancashire and Suffolk, and the majority of documents relate to these counties.
The five hundred Derbyshire documents comprise slightly over half of the collection. The majority concern Longford and its descent over seven hundred years through the families of Longford (from c.1200) and Coke (from 1615). Included is the purchase deed whereby this property was acquired by Sir Edward Coke from the trustee of the last male owner, Nicholas Longford (CRU/294), and also the indenture by which it was settled on his youngest surviving son Clement Coke, on his marriage to Sarah, daughter of Alexander Reddish of Reddish, Lancashire, and great-neice of Nicholas (CRU/304). Other documents relate to the manors of Wherstead, Bourne Hall and Pannington in Suffolk, and estates in south-east Lancashire, notably Reddish, Great and Little Heaton and Crumpsall, all in Manchester parish. There are also documents concerning the former owners of these properties, the families of Longford of Longford, Reddish of Reddish, Hulton, Langley, Prestwich, Browne, Radcliffe and Hall. The collection is especially noteworthy for the very long chronological span of documentation for several estates, including Longford (332 items, 12th-19th centuries), Wherstead (108 items, 13th-18th centuries), Reddish (95 items, 13th-18th centuries) and Great and Little Heaton (65 items, 13th-17th centuries).
The collection is particularly rich in manorial court records and allied documents. In particular there are lengthy series of court rolls for the manors of Bourne Hall in Wherstead, Suffolk (13th-18th centuries) and Longford, Derbyshire (14th-17th centuries). Other rolls are those for Haddon (14th-15th centuries), Newton Solney (14th-16th centuries), and Hathersage (16th century), all in Derbyshire, and for Wherstead and Goddelsford, i.e. Gusford Hall (17th-18th centuries) in Suffolk. The earliest roll is one of 1276, from Bourne Hall. In addition to court rolls, court books for Bourne Hall and Wherstead (1627-1640) and for various courts (1560-1571) of the Reddish family, held at Prestwich and Reddish, also occur. There are also 15th-century account rolls of the bailiffs and collectors of rents for Longford and North Wingfield, Derbyshire. Among rentals are those for Barlborough, Hathersage, Longford and Newton Solney, all of 1476, with two 18th-century ones for Longford; two for Bourne Hall (16th century) and two, in early copies, for the Priory of St Peter and St Paul at Ipswich (16th century); and a rental of Reddish, Crumpsall, Prestwich, Pendlebury and Tetlow (1590-1622), in Lancashire.
The collection contains a number of significant seals, including examples of the Great Seal from the reign of Henry III onwards (e.g. CRU/928, 1252); perfect specimens of the Duchy of Lancaster seal (CRU/660, 1577); and of the rare Statute Merchant Recognizance Seal of Wigan (CRU/599, 1391). Unfortunately imperfect, although surviving in large fragments, are the seal, with secretum, of Philip de Thame, Prior of the Hospital of St John of Jerusalem in England (CRU/204, 1377), and the common seal of Ipswich (CRU/730 and CRU/731, 1610). Naturally there are also numerous private seals, including those of John de Saucheverel (CRU/925, 1197, a phoenix); Robert de Ferrieres, son and heir of William de Ferrieres, formerly earl of Derby (CRU/929, 1262, a bust); Michael, son of Nigel de Bupton (CRU/926, late 12th/early 13th century, Samson slaying the lion); Sir William de Cantelowe and Maud his wife (CRU/18, 1371); William Fitzherbert of Norbury (CRU/213, 1390); Thomas la Warre (CRU/43, 1405); Sir William Thirning (CRU/44, 1405); and Sir Nicolas de Longford (CRU/931, 1475). An unusual seal, though imperfect, is that of Richard Swyfte, the King's carpenter (CRU/743, 1393).
