A prominent member of the mercantile community of Hull, Leversegge first appears in about 1391, when he was shipping cloth and wool overseas and importing wine from Gascony. He dealt regularly in these commodities over the next ten years at least, being no doubt able to further his commercial interests through his appointment as a collector of the royal customs at Hull. But not all his ventures were successful, and in 1397 Richard II intervened personally in an attempt to recover cloth worth 600 nobles belonging to Leversegge and his partner, Adam Tutbury, which had been confiscated at Danzig and Elbing because of an infringement of the regulations there.
Although chiefly dependent upon trade for his income, Leversegge was himself a landowner of some consequence, either through his wife, Helen, or because of his own investment in property. The couple were married by the summer of 1397, when Leversegge used his influence as a former employee of Archbishop Arundel to secure permission from the Pope for them to choose their own confessor and make use of a portable altar. Three months later an indult granting plenary remission of sins was issued to them both, and in 1401 Leversegge’s illegitimate son, Richard, was given papal letters of dispensation allowing him to take holy orders despite the circumstances of his birth. Not surprisingly, Leversegge was held in high regard by his fellow burgesses. He was called upon to witness the wills of William Willingham and William Wilton in 1391 and 1401 respectively; and during the 1390s he acted as an executor for two affluent merchants, Robert Crosse and John Calthorp. He and his friend, Simon Grimsby II, experienced some problems in collecting the debts owed to Calthorp, and as late as 1401 they were still involved in litigation over the deceased’s estate.
It looks very much as if Leversegge died at about the time of his replacement as collector of customs in October 1411. In the following year his widow, Helen, was taxed upon an estimated income of £20 p.a. from land in Hull, Cottingham and Beverley, but no more is heard of her after this date. Much later, in August 1440, Joan, the widow of John Fitling (Leversegge’s colleague in the Parliament of 1407), left £25 for masses to be said in the chapel of the Blessed Virgin, Hull, for the souls of John and Helen Leversegge, which suggests that they may well have been her parents. There is also reason to suppose that Leversegge was connected with the influential Frost family of Hull and Beverley, and thus by marriage with Thomas Holme, one of the wealthiest merchants in York. Certainly, in his will of August 1421, Thomas Frost set aside the reversion of £270 in cash to pay for masses for the souls of various kinsfolk, including the subject of this biography.
