Brock was probably the son of a minor Devon lawyer of the same name, who was still active as an attorney in the Westminster law courts in the early years of Henry VI’s reign and apparently survived into the 1430s.
It is possible that this was a conscious decision on his part, for throughout his life he maintained a wide-ranging and profitable private legal practice. He was accredited as an attorney in both King’s bench and common pleas and also regularly appeared as a pledge in Chancery.
A witness statement made by Brock in the court of King’s bench in the summer of 1442 provides a rare glimpse of his professional activity. Sworn to give evidence in a suit over the alleged forgery of a royal writ of sub poena by John Medelond*, Brock described how on Monday in Holy Week 1441 he had been approached by the fisherman Gervase Walsh and the merchant John Bygge, both from Ditttisham, and that Bygge had asked him to act as counsel for Walsh. Walsh had shown Brock a writ which the lawyer had immediately deemed suspicious, as it had been sealed with white wax. Brock nevertheless instructed his client to keep the day in court set in the writ. Later, he had confronted Walsh’s opponent, Andrew Fyssher, another fisherman, from Street, who had sued out the writ, and questioned him as to the cause of his quarrel with Walsh and the name of the lawyer who had procured the writ for him. As a result of this information, Medelond was arrested and placed in the Marshalsea until he secured his release on bail.
Brock’s extensive legal practice brought him substantial rewards, at least some of which he invested in land. By the early 1430s he was seised of lands in Dean Prior, while at the time of his death he also held the manor of Hampson, as well as scattered holdings at Washbourne, Bow, Corndon, Farleigh, Harbourneford, Hernaford, Lillisford and North Tawton, altogether said to be worth in excess of £25.
There is no indication that Brock became involved in the violence which swept south-western England in the mid 1450s, even though he had maintained his links with the Courtenays of Boconnoc. In particular, Sir Hugh Courtenay was forced to draw upon his services in 1450 when he was indicted for piracy and imprisoned in the Tower and could only regain his freedom by providing substantial sureties. One of these sureties was Brock, who pledged the huge sum of 1,000 marks.
Brock’s later career is largely obscure. He probably owed his nomination as reeve of Totnes during the first year of the reign of Edward IV as much to his longstanding links with the Pomeroys as those with the Totnes authorities. Nevertheless, the latter continued to employ him into the 1460s, even though he had on occasion found himself in opposition to some of the leading men of the town.
