General Notes

The manor of Esseover (Ashover) at the time of the Domesday Survey was held by Serlo under Ralph Fitzhubert, and it had then its priest and church. About the beginning of the thirteenth century it was divided between two heiresses, who married a Willoughby and a Deincourt. The latter moiety was subsequently inherited by two sisters, who married Reresby of Lincolnshire and Musters of Nottinghamshire; and the share of the Musters was shortly afterwards divided between two sons, from one of whom a portion passed to the Piereponts. The original manor of Ashover was thus divided into four, which became known as New Hall, Old Hall or Reresby's, Muster's, and Pierepont's manors. The Reresbys also acquired Willoughby's share in exchange for their interest in the manor of Pleasley. They were a family of some distinction, and on several occasions filled the office of high sheriff. Newhall, afterwards called Eastwood Hall, remained in the possession of the Reresbys till 1623, when the trustees of Sir Thomas Reresby sold it, together with the advowson of the church, to the Rev. Emanuel Bourne, then rector of Ashover.
