The material dates from the thirteenth century to 1927. The deeds, of which there are 120, reflect the family history. Most early deeds relate to estates in Nottinghamshire and surrounding counties prior to their ownership by the Parkyns. The later deeds include estates in Nottinghamshire, Derbyshire, Leicestershire and Kent.
Of the 100 letters in the collection, 75 are to or from Sir Thomas Parkyns, the 2nd baronet. They concern family and estate matters, and touch upon his public and social activities.
Many of the manorial records date from the same period, the early eighteenth century, when Sir Thomas was lord of the various manors. Those concerning the Bunny estate date back to the fifteenth century when the manor was in the hands of the Illingworth family, but also cover Richard Parkyns' lordship in the early seventeenth century.
The legal papers follow the same pattern as the manorial records, but run into the eighteenth and nineteenth centuries.
There are extensive genealogical notes and pedigrees written by Mansfield Parkyns, and some Arabic maunscripts collected by him during his travels.
