John Saunderson of Grimesthorpe was a tanner. In his will of June 1602, he gives:
The residue of his property he bequeaths to Jennet, his wife, and Edward Saunderson of Sheffield, tanner, executor. Robert Saunderson and Richard Allen, supervisors of the will.
Robert Saunderson - later Bishop of Lincoln, was the son of Robert of Guilthwaite, Mentioned in the Will of John, above, at the date of the will, he was 14 years old.
Bishop Saunderson was born at Sheffield, as were brother William and sister Elizabeth. It was soon after that their father settled at Guilthwaite.
Hunter (Hunter's Hallamshire), thinks that his move here was connected with his guardianship of Thomas, son of Thomas Stringer of Whiston, to which he was appointed on 9th March, 1587-8. Thomas Stringer, the elder, was employed by The Earl of Shrewsbury in the management of their estates. Robert, the Bishop's father along with Gilbert, Earl of Shrewsbury was a sponsor at the baptism of Gilbert Sheldon, son to a retainer of the Earl, afterwards Archbishop of Canterbury; favours the supposition that he might succeed Stringer in his appointment.
Robert Sanderson the elder, bought the Guilthwaite estate from Gregory Starkie of Markham, Notts. He sold the estate in October 1603 to George Westby for £710. He moved to Blythe where he died November 14th 1609, and was buried there.
Margaret Rawson, daughter of John Rawson of Upperthorpe married Nicholas Saunderson (d.1580) at Sheffield in 1575.
Nicholas Saunderson(b. 1600) He had several children, among whom were Mary, the second wife of John Cart, Rector of Handsworth, and Martha, wife of Gilbert Morewood.
Edward Saunderson - the brother of Nicholas, also had numerous children, most of whom lived in the Sheffield area.
There were five Saundersons, Lords, Viscounts Castleton of the kingdom of Ireland, the last of whom was created Baron Saunderson of Saxby of Lincoln, by King George 1 before his Coronation; in the next year Viscount Castleton of Sandbeck, and in 1720 Earl of Castleton. All the honours became extinct on his death without issue in 1723. He left Sandbeck and other property to Sir Thomas Lumley K.B., a younger son of Richard the first Earl of Scarborough - he took the name of Sanderson. On the death of his elder brother Richard, in 1739, Sir Thomas Lumley Saunderson, became Earl of Scarborough.
