Warner, who was descended from a family established at Gestingthorpe in Essex since at least the early fourteenth century,
Such official business aside, Warner, like many other lawyers of his standing, busied himself with the affairs of numerous private clients, frequently serving as an attorney, arbiter and feoffee, standing surety in the law-courts and attesting his neighbours’ property deeds. His network of clients stretched across the city of London and into its immediate hinterland. He maintained connexions with his native county of Essex by assisting the future Speaker Richard Baynard* and his third wife in their property transactions,
Westminster Abbey was not alone in regularly offering the under sheriff douceurs of up to a mark of silver,
By contrast, Warner seems to have acquired little if anything by his three marriages. Of his first wife, Cecily, nothing is known, except for her name. The parentage of her successor, Eleanor, is equally obscure, but she is unlikely to have brought him any London property, since in 1418 the couple had to lease a vacant plot in the parish of St. Martin Ludgate on which to build a house.
It is not clear what motivated Warner to seek election to the Parliament of 1425. He was not unfamiliar with parliamentary affairs, for his care for the fixtures of Westminster Hall regularly demanded his attendance at Westminster when the Lords and Commons were in session. Moreover, in his capacity as under sheriff he was more often than not present at the parliamentary elections in the Middlesex county court, and although the standard diplomatic practice adopted when drawing up the election indenture preserved the fiction that the sheriffs of London and Middlesex had presided in their own persons (thus allowing Warner to take his place among the attestors countersealing the document), the reality of the under sheriff’s leading part in proceedings is hinted at by occasional engrossments.
In spite of his profession, Warner does not appear to have been a litigious man in his own right. His appearances in the law courts on his own affairs were few and far between, mainly dating from the later years of his life, after his surrender of the Middlesex under shrievalty. Thus, in the summer of 1429 he quarrelled with one John Ogham over a bond for £20; that autumn he accused one of his tenants at Stanwell of unlawfully retrieving livestock which he had seized in distraint for customary services; and a year later he was embroiled in a suit of trespass against a rather more prominent opponent, William Hulles, the prior of St. John of Jerusalem in England, probably in connexion with Staple Inn or another of his properties in Holborn in the vicinity of the Temple.
By 1436 Warner’s estates in London, Middlesex, Essex, Oxfordshire and Surrey were believed to be worth at least £50 p.a.
It was probably on account of his advancing years that in 1428 Warner had been replaced as under sheriff, and his exemption from office-holding in London in 1430 explicitly referred to his ‘infirmities’.
In December 1439 Margaret Warner procured letters of denization which allowed her to hold land in her own right.
