As a member of one of the richest and most influential families in Southwark, it was natural that John Mucking should so often have been returned by the burgesses to Parliament. His father before him sat for the borough in 1362 and 1365, having by that time chosen to invest his profits from the wine trade in local property. John’s younger brother, Nicholas, a clergyman, pursued an equally successful career: in 1374 he became rector of St. Olave’s church in Southwark, obtained the treasurership of St. Paul’s cathedral 20 years later, and by the time of his death in 1424, had been appointed master of the college of St. Lawrence Pulteney.
Although Mucking appeared with his father in both May 1370 and February 1378 as a witness, and in 1372 as one of Sir Nicholas Carew’s feoffees for land in Southwark, he seems to have set up in business on his own account while still a relatively young man.
A number of more private quarrels at home attracted his immediate attention: between March 1387 and June 1398 he became involved in no less than six lawsuits, evidently at no little cost to his purse, if not his reputation. The first of these disputes was with the prior of Southwark, and the substantial sureties of £100 offered by both men as a guarantee of their future good conduct suggests that their initial disagreement had been serious. The summer of 1389 saw Mucking’s appearance as defendant in a case brought by John Forteneye, his own apprentice. The latter had been imprisoned in July of that year for attempting to defraud a Gascon merchant of wine worth £57 18s.4d., although the mayor’s court found that by his refusal to honour an existing contract Mucking himself, rather than his agent, had committed the offence. He was ordered to refund the full purchase price of the wine and suffered a brief period of imprisonment until this had been done. Equally serious charges were levelled against him at this time by his neighbours in Southwark, who complained to the King’s Council about the brothels, ‘conuz entour toute la ville la citee de Loundres auxi tenuz pour le treshorrible lieu de pecche use deinz nostre Roialme d’engleterre’, which he and four other leading burgesses had set up in St. Olave’s parish. This area was already notorious as a refuge for criminals and receivers of stolen goods; and although Mucking was summoned to attend a meeting of the Council in July 1390, there is no evidence of any firm measures being taken against him. Three years later he again came before the mayor’s court apparently because of some unspecified quarrel with Richard Spencer, a London spicer. Both men were required to enter into bonds of £100 pledging their readiness to abide by the decision of four independent arbitrators, but the outcome of the case remains unknown. In the meantime, in March 1390, Mucking was summoned to perform jury service at an assize of novel disseisin being held on Sir Roger Clarendon’s property in Southwark. It was shortly afterwards that he and other members of his family were themselves brought before the local justices of assize by Isabel Exeter, but they had little trouble in establishing their title to two messuages in the borough which she claimed as her own.
Mucking does not appear to have incurred any disadvantage as a result of his various brushes with authority. On the contrary, he was among the 24 Londoners ‘in secundo gradu potentionibus civitatis’ chosen in June 1392 to accompany the mayor and corporation on their deputation to the King at Nottingham. Given the extreme hostility then felt by Richard II towards the City and the complete powers of negotiation vested by the commonalty in its representatives, it is evident that Mucking enjoyed not only the respect but also the confidence of his fellow citizens. The meeting was not a propitious one resulting in the immediate suspension of the City’s elected officers and the appointment of a warden to supervise the business of government. Henceforward, Mucking chose to spend most of his time in Southwark and evidently abandoned his interests north of the river, perhaps as a direct result of his disillusionment with political life. During the Easter term of 1393 and again three years later he was named among the defendants in two assizes of novel disseisin concerning tenements in Southwark, but on both occasions his involvement was merely that of a feoffee.
Apart from his intermittent activity as a tax collector for both Southwark and Surrey, nothing more is known of Mucking until December 1412, when the prioress of the house of the Blessed Mary of Cheshunt began an action in the husting court of London for the recovery of a tenement in the City which she claimed that Mucking, his brother Nicholas and another member of their family had seized without any legal title. None of the three men ever appeared to answer her accusations, probably preferring to settle the matter out of court. In May 1415 Mucking was once more named, but not sworn, as a juror at the borough assizes.
