Little is known of Melreth’s origins although his family almost certainly hailed from Meldreth in Cambridgeshire, and he remembered the parish church there in his will. He maintained a connexion with the county throughout his life.
Melreth built up an impressive range of business contacts, including trading partners such as the prominent grocer Thomas Canynges*, and customers from various parts of the country. Gifts of goods and chattels, made as security for the repayment of debts for goods purchased on credit show that he had dealings with many fellow London mercers, including leading members of the trade like William Cantelowe*. Similarly, perhaps as a result of his links with Canynges, he became involved in business transactions with several individuals from Bristol as well as merchants from York. Thus in July 1430 he and John Denys of Bristol entered into mutual bonds in £200 for the settlement of a dispute between them by the arbitration of John Mitchell I* and Robert Russell I*.
Melreth’s commercial success put him, like many other London merchants, in a position to advance badly-needed cash to the Crown. In May 1436 he and Robert Large* lent sums of £40 and £66 6s. 8d. respectively, and in return, in September of that year, they – as joint owners of a ship called The Marie – were granted letters of marque for two months, which enabled them to man and arm their vessel and to take the chief share of any cargoes which they seized from enemy ships. Canynges was another of the owners of this vessel, and on 17 May the following year (two days after Melreth had provided a further advance of £60 to the Exchequer) he and Melreth were granted a similar royal licence, although on this occasion they were permitted to fit out another three ships, two balingers and a barge as part of a convoy which was to accompany The Marie to Arnemuiden in Zeeland, on this occasion for the purpose of legitimate trade.
Over the course of his career, Melreth acquired a substantial amount of property, and in 1436 his holdings in the capital and ‘elsewhere’ were said to be worth an impressive £80 p.a.
There is little doubt that Melreth’s financial standing, although already the equal of most of his fellows, was significantly boosted through his marriage (probably his second) to Beatrice, the coheiress of a wealthy Sussex family, who had recently been widowed following the death of her first husband, Reynold Cockayne, a prominent landholder in Hertfordshire and Bedfordshire. The marriage may well have owed something to a connexion which Cockayne himself had established with Melreth’s craft: in 1414-15 he had been admitted to the freedom of the city by redemption through the Mercers’ Company, and it is probable that Melreth, who entered the livery of the craft about the same time, knew him personally and established a connexion with the family which paved the way for his later marriage to Cockayne’s widow.
A more serious dispute over the division of the Waleys estates pitted Beatrice and her sisters against Robert, Lord Poynings. The death of their brother John Waleys in about 1423 had left as his heir male his cousin William Waleys, a minor of unsound mind (known in the family pedigree as ‘the idiot’). Having purchased his wardship, Lord Poynings proceeded to occupy the principal Waleys manor of Glynde, but William’s title was challenged by the four Waleys sisters and their husbands. Eventually, the matter was subjected to the arbitration of William Chaunterell, serjeant-at-law, and the recorder of London, Alexander Anne*, who in their award made in November 1436 found against Poynings, who was ordered to surrender Glynde. On 12 Dec. William Waleys was formally disseised, and the coheirs then partitioned his Sussex estates between them, the Melreths taking as their share the manors of Hawkesden and Bainden.
Melreth’s involvement in the property transactions of others is well documented. From 1420 onwards he frequently acted as a trustee with, and on behalf of, other prominent mercers, notably Estfield and Frowyk. In 1425, for instance, the three men were among those granted estates by the executors of Richard Whittington†, who were then in the process of assembling an endowment for the college for priests and the almshouse which were to be founded out of the late mayor’s estate. Some years later they acted as feoffees for property held by William Cantelowe. They were also closely connected with a Cambridgeshire merchant named John Pycot, and in 1420 all four men were granted property in Catte Street by William Oliver†. Ten years later they collectively brought a plaint of intrusion against Oliver in the mayor’s court. On another occasion both Estfield and Melreth had acted as sureties when Frowyk had been confirmed as the guardian of the son of a fellow mercer. Elsewhere, Melreth also acted as both a witness and as a feoffee for St. Bartholomew’s hospital in its acquisition of property in Hendon in Middlesex.
Melreth’s civic career began in orthodox fashion with his appointment in September 1420 as one of the city auditors, a position which frequently led to higher office within the city government. He held the post for just one year, although he was chosen to do so again in the autumn of 1424. While still in office, in the summer of 1425 he was named as a constable of the Westminster staple, an office which he would retain for eight years. Meanwhile, in the autumn of 1425, he relinquished the auditorship and was elected one of the sheriffs of London and Middlesex. This term of office saw some political controversy as the sheriffs were called upon to act against the tailor and radical leader Ralph Holand who had challenged the city ordinances governing the election of the mayor and sheriffs.
Although Melreth, unlike some of his peers, did not stand out for regular service on the many city committees appointed for a variety of purposes during the 1420s and 1430s, it is clear that his civic career progressed steadily. In the spring of 1430 he was chosen alderman of Broad Street Ward, and thus came to be a regular participant in meetings of the court of aldermen and in elections of the mayors and sheriffs of London.
Inevitably, perhaps, Melreth also became involved in disputes of his own: in March 1442 a quarrel with Geoffrey Yernemouth was submitted to the arbitration of Geoffrey Feldyng* and others, and further quarrels marked the last few years of his life. During the course of these he came up against some of London’s most prominent citizens, including Thomas Burgoyne* and Geoffrey Boleyn*, to whom he was bound in £100 in October 1444 to abide by the award of arbiters.
On 18 Jan. 1446 the common clerk of the city noted the death of ‘W. Melreth alderman’ in his record of the proceedings of the court for that day.
