Feriby enjoyed a short but successful career as a local lawyer. There is little precise information about his family background.
The first reference to Feriby occurs in November 1410, when he was named as a mainpernor in Chancery along with two prominent Lincoln men, John Bigge† and Robert Walsh*. His first appointment to an ad hoc commission of local government followed three months later and when Sir Robert Hilton* became sheriff in November 1414 he took up the responsible office of under sheriff. Clearly he was already well established among the community of minor local lawyers who filled such roles, and it may be that he had a particular connexion with Hilton, whose election to Parliament he attested on 9 Mar. 1416ilton.
This indictment did not interrupt Feriby’s career. Indeed, his acquisition of the manor of Darby in November 1419 enhanced his status. On 16 Nov. 1420 he was named as the Lincolnshire escheator, and nine days later he headed the list of 16 attestors to the county parliamentary return. He was serving as escheator when, in the following March, he was one of the parishioners of Barton-upon-Humber who concluded a dispute with the abbot of Bardney, the rector of the parish church, over the extent of the abbey’s financial responsibility for the cost of protecting crops.
At about this time a second marriage extended Feriby’s landed interests beyond the north of his native county. His second wife was one of the four daughters and coheiresses of a Nottingham merchant but, of greater importance for our MP’s career, she was the widow of an important citizen of Lincoln.
Feriby’s new city interests did not, however, lead him to abandon his part in the wider affairs of the county. A fortnight after his election to the 1423 Parliament he was in technical breach of the electoral statutes by attesting the county return. He again appeared as a mainpernor in Chancery in January 1425 on the appointment of Robert Hilliard to the Lincolnshire shrievalty, and his legal qualifications gained further recognition in the following March when he was promoted to the quorum of the Lindsey bench. Soon after, he recurs in his familiar role as an attestor of elections, being present at both the county election of 26 Mar. and the city election of 2 Apr., again in technical breach of statute. He also attested the following county election of 14 Jan. 1426 and acted as one of the pledges of Hamon Sutton I* on his return to represent Lincoln a week later.
When added to his own lands and earnings as a lawyer, the inheritance of Feriby’s second wife made him a man of some wealth. In the subsidy return of 1436, described as ‘of Frodingham’, he was assessed on an income of £20 p.a.
As a lawyer Feriby was very active in the affairs of his neighbours. Besides Cumberworth, for whom he was a feoffee from the autumn of 1429, he acted in the same capacity for his fellow Lindsey landholders, Sir Thomas Beelsby of Beelsby, Patrick Skipwith*, John Haytefeld of Flixborough, and Thomas Mitford of Luddington. On 3 July 1423, along with other Lindsey landholders, he witnessed a charter, oddly dated at London, relating to the Strange of Knockin manor at West Halton.
