The Botreaux were an ancient Cornish family who had been elevated to the baronage in the reign of Edward III. The identity of the man who represented Liskeard in 1423 cannot be established beyond reasonable doubt, but it is probable that he was the London draper of that name, who held estates in Cornwall, rather than his namesake, the Hampshire esquire William Botreaux II*, who later sat in several Parliaments as Member for Wilton. Equally, it is uncertain exactly how William was related to the Lords Botreaux of Boscastle, or, indeed, whether his birth was legitimate. Nevertheless, throughout his life he maintained connexions in his native county of Cornwall, and also with his Botreaux relatives.
No details of William’s apprenticeship or admission to the freedom of London have been discovered, but he was evidently well established in the drapers’ trade by the second half of Henry IV’s reign, when he was supplying cloth to the King’s great wardrobe.
In 1419 Botreaux was said to reside in London’s Cheap Ward, and it is likely that property in the parish of St. Mary le Bow, which in 1433 was settled on his eventual executors in a series of transactions involving the Chancery clerk Robert Syreston† and a number of other Cornishmen, was in fact his.
It seems that Cornish affairs also lay at the root of Botreaux’s only recorded return to Parliament in 1423. There is a sense that the Botreaux family was seeking to promote their interests, whatever they were on this occasion, for the draper’s fellow member for Liskeard was Robert Chiselden*, one of the retainers of William, 3rd Lord Botreaux, while the baron’s uncle, Sir Ralph Botreaux*, sat alongside him in the Commons as one of the Cornish knights of the shire.
William Botreaux died in the early months of 1432. The execution of his will was entrusted to his wife’s brother, John Trenewith, the London mercer Everard Flete*, the lawyer Thomas Cokayn*, the draper John Norman and the haberdasher Walter Peryn, who were still engaged in litigation over its terms in the early 1440s.
