The Yorkshire Mountforts were a junior branch of a Somerset family, anciently established at Nunney, which failed in the main line in the fourteenth century. By that time the junior branch had settled, in somewhat unusual circumstances, at Hackforth in the Richmondshire parish of Hornby in the North Riding. In 1320 Elizabeth, wife of Sir Alexander Mountfort, claimed that her brother, Sir Thomas Burgh, was impotent and thus that, as his two avowed sons were bastards, she was his heiress-presumptive. After her brother’s death in 1322 she acknowledged that this claim was false, but she was able to extract a price for that acknowledgment. Her nephew, John Burgh (d.1330), conceded to her his manor of Hackforth and his other Richmondshire lands in return for her renunciation of any claim to his other lands in Yorkshire and Cambridgeshire.
Before the time of our MP the Mountforts of Hackforth played only a modest part in their new county’s affairs. Our MP’s father, the brother of Alexander Mountfort (who had died young), had but a brief adult career. Inheriting as a minor in 1395, he proved his age in 1405 and died shortly before February 1417.
Mountfort’s adult career had a slow beginning. In 1424 his mother and her second husband, John Pygot of Ripon, brought an uncontested and presumably collusive action against him for her dower in the family lands at Nunney and nearby Trudoxhill.
If, however, Mountfort’s standing was increasing in Richmondshire, his lack of connexions in Somerset seems to have prompted him to surrender the family’s claim to Emborough. That claim had been pursued during his minority, but in July 1438 he joined with his mother and brother Christopher, parson of the North Riding church of Kirklington (the advowson of which belonged to John Wandesford, husband of their sister, Eleanor, and another prominent Neville retainer), in releasing their claims to the manor to a group headed by the then lord of Emborough, Sir Ralph Butler of Sudeley. The deed of quitclaim has a curious feature. Although dated at Winchcombe in Gloucestershire, the witnesses were all Yorkshire neighbours of our MP, headed by his father-in-law, Justice Strangways, and including Christopher Conyers of Hornby, Richard Weltden and several other members of the Neville affinity. This implies that Mountfort was already himself becoming an important member of that affinity, and this supposition is amply borne out by what is known of the second half of his career. He is named in a partial list of the retainers of Richard Neville, earl of Salisbury, dating from the late 1450s, when he was in receipt of a fee of £6 13s. 4d., and it is probable that he, like many of the others named in that list, was a retainer of long-standing, even if almost all were in receipt of only pro tempore fees.
By this date Mountfort was a knight. He is first so described in Michaelmas term 1449, when plaintiff in an action of trespass, and it may be that the occasion of his dubbing was the disastrous campaign against the Scots which saw the English defeat at the battle of Sark on 23 Oct. 1448.
Despite Mountfort’s obvious attachment to the Nevilles, it seems that he did not join the Neville force which gathered at Middleham in September 1459 for the campaign which ended badly for the Yorkists at Ludford Bridge. Had he done so it is hard to imagine that he would, on the following 21 Dec., have been named to the commission of array in the North Riding explicitly issued to resist Yorkist rebellion.
Mountfort’s election to Parliament proved to be the final major event of his life. Precisely when he died is unknown, but he was not reappointed to the bench after Edward IV took the throne, and it was clearly his son who was named on various ad hoc commissions by the new government in May 1461.
