The small deposit of estate papers for the Langley family arrived in the Brynmor Jones Library in 1974 as part of the larger deposit of legal and estate papers from Crust Todd and Mills, Beverley solicitors. They comprise estate papers for North Grimston, Acklam, Leavening as well as a bundle of papers for Kendall Farm, Driffield. An abstract of the title of Richard Langley covering estates 1722-1803 indicates that the Langley family owned the manors of North Grimston, Sherburn, Fimber, Leavening and West Heslerton as well as a moiety in the manors of Crosby and Swine Brompton, the manor of Hagthorpe and also of Driffield, the latter including all fairs, markets and tolls for Great Driffield and Little Driffield. Their other estates included Wykeham Abbey, Scagglethorpe, Settrington, Acklam, Hutton Cranswick and Riston. They also held the advowson of Wold Newton (Haltemprice).
A number of papers in the collection related to the estates of Richard Langley (d.1817) and they include rentals and accounts for estate improvements. There is some correspondence between Lord Middleton and John and Robert Lockwood, solicitors, as well as the marriage settlements of Ralph Creyke and Jane Langley (1771) and Thomas Thornedike and Christian Waterhouse (1662). Wills are those of Thomas Langley (1722), Richard Langley (1754), Elizabeth Langley (1757) and Boynton Langley (1769).
