Hammoon (originally Ham Mohun), a vill situated on the banks of the river Stour in north Dorset, was granted to William Mohun by the Conqueror and continued in an unbroken male line in a cadet branch of his family from the late twelfth century until the death of our MP. The main line of the family was seated at Dunster castle in Somerset, and Hammoon was held of the barony of Dunster throughout the Middle Ages.
Another part of Mone’s inheritance apparently came from his grandmother Joan, who was a member of the family of Norris of Normanton in Wiltshire.
In Mone’s youth his guardian, John Jordan, married him to his daughter Joan, who although she was not an heiress at the time was nevertheless destined to inherit the estates of her parents at some point in the late 1430s or early 1440s. When her father, who for many years held the post of steward of Dorchester, died in 1427, he left a son and heir, John, with whom our MP had dealings regarding a moiety of the manor of Freeland in Piddletrenthide three years later. It is uncertain whether this younger John Jordan died without issue or whether he voluntarily relinquished his lands to his brother-in-law, but not long after 1439 the entire Jordan inheritance passed to the Mones. Our MP conveyed Freeland to Cardinal Beaufort and others in 1444, to facilitate its transfer to Hyde abbey.
The early part of Mone’s career is poorly documented, although it may be speculated that during Henry V’s reign he spent time in Normandy serving with his lord Sir Hugh Luttrell.
Mone’s close involvement in the affairs of William Stafford and his wife were to continue until his death 30 years later, and on at least one occasion led him to break the law. When Stafford quarrelled with his niece’s husband, Sir James Butler, heir to the earldom of Ormond, Mone stood by him, even when the quarrel erupted into violence. He was allegedly among those of Stafford’s associates who stole from Butler 16 horses worth £30 and goods worth £10 at Nether Kentcombe on 5 Sept. 1444, in the course of a raid in which Butler’s servants suffered assaults,
Earlier that same year Mone had entered the Commons for the second time, sitting in the Parliament at Bury St. Edmunds as a representative for the city of Salisbury. There is no ready explanation as to why the citizens chose him, rather than one of their mercantile elite, although his links with the chancellor may well have been a factor in their decision. Yet, he was no stranger to the deliberations of the city’s assembly. As John Mone ‘gentleman’ he had been a member of the council of 48 for nearly three years, and had served the city as an auditor; indeed as recently as November 1446 he had been employed in this capacity and active with regard to securing a reduction of the parliamentary subsidies expected from the city by the Crown.
Following William Stafford’s death in 1450 at the hands of the rebels under Cade, Mone provided constant support for his widow, Katherine, who had only shortly before entered her share of the valuable Chideok inheritance. In the following year, on her second marriage, to John Arundell of Lanherne, she appointed Mone as her attorney to receive seisin of the numerous manors Arundell had given to her at their betrothal, and in July 1452 he conveyed to the couple the Stafford manor of Southwick, which Katherine was to hold for her lifetime.
Yet while always ready to support his friends, Mone had his own business interests to consider, and foremost among these were his activities as a sheep farmer and exporter of wool. At Normanton he had ‘le lez’ for 200 sheep, and a discredited report of 1473 held that there were as many as 14,000 grazing on his lands in Dorset. The 1,100 recorded there shortly after his death seems a more realistic number, yet there can be no doubt that sheep-farming was a prime source of his wealth.
During the period of the civil war from 1459 to 1461 there is nothing to show whether Mone offered tangible support to either side, although it may be supposed that his long-term disagreements with the earl of Wiltshire would have predisposed him to oppose Lancastrian rule. This predisposition was perhaps reinforced by his long involvement in the affairs of the Staffords and role as mentor to the son and heir of his old friend William Stafford. He, Humphrey Stafford IV*, became a favourite of Edward IV, and having risen to be Lord Stafford of Southwick was created earl of Devon by him. As a feoffee of the Stafford estates, Mone made settlements on Humphrey’s marriage to Isabel de la Barre, and in 1466 he asked him to be a trustee of his own property.
While there was no doubt of Earl Humphrey’s loyalty to Edward IV, others of the gentry of Dorset clearly became divided in theirs the following year, when the duke of Clarence openly opposed the rule of his royal brother. Mone appears to have been one of those suspected of outright disloyalty. When, in April 1470, John Twyneho† was bound to the King in 1,000 marks to attend upon the constable of England, Mone, together with another long-term member of the Stafford circle, Thomas Martin*, joined Twyneho’s father in bonds in 500 marks as security for his good behaviour while in custody.
Other financial matters concerning Mone in his final years included the pursuit of (Sir) Nicholas Latimer* and John Newburgh II* for 500 marks owed him under a statute staple for merchandise sold at Poole in 1466,
Our MP was the last of the Mones of Hammoon: when he died, on 6 May 1479, his heir was his grandson John Trenchard. Besides the normal writs de diem clausit extremum issued to the escheators of Dorset, Hampshire and Wiltshire on 6 June and 6 July to conduct inquisitions post mortem, a special commission of inquiry into his lands was appointed on 5 July, addressed to William Huddesfield†, the King’s attorney, and John Byconnell*, whose particular brief concerned the former Godmanston estate.
In the meantime, a major crisis had beset Mone’s family. Having rebelled against Richard III, his grandson John Trenchard was attainted in the Parliament of 1484, and his estates were forfeited and granted by the King to one of Mone’s former feoffees, Morgan Kidwelly.
