The Bosons had been established at Screveton in south Nottinghamshire and Long Clawson in north Leicestershire since the time of Henry III,
In December 1435 the young Henry secured royal letters of protection as about to depart for France in the retinue of the old soldier, Richard Wastnes, who was very probably a relative of his present or future brother-in-law, John Wastnes*, but this is the only evidence that he saw military service. He was assessed on an annual income of £40 in the tax returns of 1436, a level of wealth sufficient to make it surprising that he was appointed to a lowly commission of tax collection in 1437.
Shortly after his return, Boson received, in May 1446, a small grant of royal favour in the form of an exemption from local administrative office.
Boson’s election to Parliament marked the pinnacle of his brief career. He went on to attest the next Nottinghamshire election in October 1450, when John Wastnes was returned, and two months later, despite his exemption from office, he was appointed escheator. By this date, however, he was probably already ailing and he was not destined to see out his term of office. On 17 Feb. 1451, when not yet 40 years old, he drew up his will, and, on the following day, Wastnes was appointed to replace him as escheator.
Boson wished to be buried in the church of Long Clawson next to the tomb of his father. His bequests were remarkably modest: £2 to the fabric of the church, the same sum to his uncle, William, £1 to John Draper of Flintham; and to his sister, Joan Wastnes, a bowl called ‘le Note’ decorated with the Boson arms. He appointed his wife, his uncle and Draper as his executors, with the Yorkshire esquire, Nicholas Wortley of Wortley, as supervisor. A week later his will was proved. Its bequests are no reflection of the testator’s wealth. Very shortly before his death Boson had been assessed for taxation on an annual income of as much as £74. This increase in comparison with his assessment of 1436 is particularly significant in the context of the under-assessment which characterized the later tax, and strongly suggests that his landed resources had been considerably augmented between the two dates. It is unfortunate that his landholdings are not better documented, but there can be little doubt that, at an unknown date between 1436 and 1450, he inherited his mother’s Usflete lands, which, presumably, had not come into his possession on her death in 1435 because they had been in the hands of feoffees seised to the use of her will. The acquisition of this property explains why his will was drafted, not at Syerston or Long Clawson, but at Ousefleet in the West Riding.
A Chancery petition dating from after Boson’s death provides a revealing insight into his career. A Lincolnshire gentleman, Richard Halmer of Weston near Spalding, complained that, as an eight-year-old boy in about 1443, he had been forcibly abducted from his mother by the Household servant, Hugh Wythom*, and taken into Nottinghamshire, where he was sold to our MP. Boson mistreated him, putting him to the plough and other servile occupations, while his mother laboured against both abductor and purchaser for his return. Although she spent 40 marks, which she raised through the sale of part of her son’s landed inheritance, the defendants ‘were of suche myght and power and gat them suche assistence’ that she could not prevail, and hence he remained in Boson’s custody until his death. If this petition is to be taken at face value, it suggests that the misdeeds of Household men in the localities in the 1440s were not confined to the servants of William, duke of Suffolk, and James Fiennes*, Lord Saye and Sele.
Boson’s will does not mention a son and heir, but he appears to have been succeeded by another Henry, who, it is said in the pedigrees, married Katherine, daughter of the Nottinghamshire knight Sir Robert Markham (d.1446) of Cotham. Their son, Sir Richard, extended the family’s estates through marriage to the daughter and heiress of James Dene of Barrowby near Grantham, but, on his death in 1524, he left five daughters as his coheiresses.
