The Grimsbys were one of the principal families of the borough from which they took their name, and had occasionally provided it with parliamentary representatives since 1332. Our MP was the first of the family to enjoy a career of more than local significance. He first appears in the records in July 1448 when he acted as his father’s attorney in the Grimsby borough court.
The Yorkist victory at St. Albans on the following 22 May marked at most only a temporary setback to Grimsby’s advancement. Indeed, the burgesses of Grimsby thought it worthwhile returning him to the Parliament the Yorkists summoned in the immediate aftermath of their victory, and he was able to make himself sufficiently acceptable to the new regime to be appointed, while still an MP, to the Lincolnshire escheatorship. His West Country post was, however, lost. Unlike his 6d. a day as a yeoman of the Crown it was not exempted from the Act of Resumption of 1455-6, and in February 1456 the mines were committed to the duke of York, who no doubt appointed his own receiver-general.
This last grant coincided with a much more important one. By 21 Oct. 1456 Grimsby was acting as treasurer of the King’s chamber. This marked the beginning of a shift in the focus of his career from Household to Exchequer. When James Butler, earl of Wiltshire, became treasurer of the Exchequer on 30 Oct. 1458 he appointed our MP as his under treasurer. Revealingly, this choice attracted the notice of the mayor of Southampton, Walter Clerk*, who wrote home from London on 2 Nov. that ‘one Grymesby that wasse Clerk of the Jowell the which made grete attendaunce about the Kynge in his Siknes’ was the new under treasurer.
As under treasurer Grimsby was an important man, and the natural recipient of further grants of patronage from the King and others. On 20 May 1457 he had been granted the wardship and marriage of a minor duchy of Lancaster ward, John Malbysshe; and in December 1458 the earl of Wiltshire’s kinsman, Reynold Boulers, bishop of Coventry and Lichfield, named him as his steward. Two more significant grants followed: in the spring of 1459 he was granted an annuity of 50 marks assigned on the duchy of Lancaster honour of Bolingbroke; and in the following August he received a licence, along with his master, Wiltshire, to export wool free of customs in compensation for £1,500 they had lent to the King for the expenses of the Household.
In the late 1450s, while no longer a young man, Grimsby added to the fruits of royal patronage the blessings of a profitable marriage, taking as his wife Anne Moton, who was many years his junior. She was a coheiress, although not one of a straightforward kind. On her father’s death in 1445 she, with her sister Elizabeth, stood as coheiresses-apparent to their grandfather, Sir Robert Moton. Sir Robert had, however, resolved to disregard both their natural rights and an entail in their favour in the interests of perpetuating his lineage in the male line through their uncle of the half-blood, William. With respect of the principal Moton manor, that of Peckleton in Leicestershire, he was successful, and of the ancient Moton lands only the small Oxfordshire manor of ‘Clare’ in Pyrton passed out of the male line.
Not long after this marriage, however, the rising courtier was transformed into a penniless exile. So great were his gains from Lancastrian patronage that Grimsby had a strong incentive to remain loyal to the cause of Henry VI, at least until that cause was proved demonstrably hopeless. Hence he took up arms for the house of Lancaster at the battles of Wakefield and Towton, and he paid the penalty by being attainted in the first Parliament of the new reign. He was unable or unwilling to adapt to the changed political circumstances as he had been able to do in 1455. Indeed, the intimate place he had held in the service of the deposed King put a particular value on his head: on 6 Mar. 1461, as one of the leading Lancastrians, he was exempted from the proclaimed general pardon, and a £100 reward was promised to anyone who should put him to death. In the following month his arrest and the seizure of his goods was ordered.
It is not known what part, if any, Grimsby played in the Lancastrian campaigns in the north between Towton and final defeat at Hexham in May 1464, but he was one of Queen Margaret’s advisers when she made the treaty of alliance with Louis XI at Tours on 28 June 1462.
Thereafter, like other former exiles, Grimsby lost no time in re-establishing himself under the restored Edward IV. Realism dictated to him that the Lancastrian cause was lost, and the restored King was aware that men of ability, whatever their antecedents, were not to be spurned. Hence, on 4 Dec. 1471, Grimsby successfully sued out his second pardon, and he was sufficiently rehabilitated to secure election for his native borough to the Parliament of the following October.
This last part of an eventful career was spent in the service of William, Lord Hastings. By May 1475, as Hastings prepared to embark on the expedition to France, our MP was well enough established in that lord’s service to be nominated as one of his feoffees. Soon after he acted as one of Hastings’s clerks in the Exchequer in his lord’s capacity as one of chamberlains of Receipt there, and it may be that his knowledge of that great department first recommended him to his new lord.
Late in his life Grimsby had married for a second time and entered into an arrangement that potentially compromised the interests of Henry as son and heir. By a fine levied in Hilary term 1479 his late wife’s inheritance was settled on one William Brette for a term of two years with remainder to our MP and his second wife, Margaret, to hold for their lives as Henry’s tenants.
