The pedigrees trace the ancestry of the Sheffelds back to a Sir Robert, who is said to have flourished in the time of Henry III.
Whatever the early history of the family, it was not until the career of our MP that the Sheffelds came to play a significant part in local affairs, and thereafter successive legal careers, each more successful than the last, brought rapid advancement. The foundations of this advancement were laid by our MP’s father, himself a minor lawyer who married an heiress. In 1430 she brought their son the small Yorkshire manor of Azerley near Ripon and some lands in West Butterwick to add to their existing estate there.
The ready cash available to the successful lawyer enabled Sheffeld to extend significantly the family estates by purchase. Two of these purchases are recorded in the feet of fines: in 1442 he bought 50 acres of meadow in West Butterwick from one Walter Castelforth; and a year later he acquired from a minor esquire, William Eston of High Burnham, several hundred acres of land in East and West Butterwick and surrounding vills. But his principal purchase came in 1445, when he paid another esquire, Brian Boys of Chilton (Durham), 260 marks for the manors of South Conesby and Gunness, to which he added, in 1448, some neighbouring lands in Flixborough and North Conesby.
Sheffeld also extended his estates by marriage, taking as his wife one of the two daughters and coheiresses of his neighbour and fellow Lindsey j.p. Thomas Santon and a kinswoman of another lawyer, John Portington, j.c.p. from 1443 until his death in 1454. It is not clear what properties she brought him on her father’s death in about 1437, but they probably comprised small manors in Santon, Flixborough and North Conesby, all in the vicinity of West Butterwick, together with some property on the Yorkshire side of the river Humber at Hessle, Tranby House and Anlaby and a reversionary interest in a larger Yorkshire estate expectant on the failure of her half-sister’s issue.
So able a lawyer was bound to be in heavy demand as an associate in the affairs of his neighbours, and Sheffeld’s connexions were both broad and distinguished. From early in his career he served as local steward for the dean and chapter of Lincoln and was retained as counsel by the Yorkshire abbey of Selby.
Sheffeld’s acquisitions of property and his connexions are the most noteworthy features of a career that was as colourless as it was successful. Its basic outline is quickly sketched. For 30 years he took an active role in local administration, probably serving, for most of that time, as Lindsey’s custos rotulorum.
The date of Sheffeld’s death is unknown. His last appointment to a local commission was in March 1465, and he was certainly dead by June 1466, when his widow was allegedly the victim of a minor offence against her property at South Conesby.
