A lawyer, Reynold was the son of a townsman from Godmanchester near Huntingdon. Technically a self-governing manor, Godmanchester did not gain corporate status until 1604. In practice, its exemptions and privileges meant it was very similar to an incorporated borough,
Of the two brothers, Robert was most in need of legal advice because for many years he and his wife were embroiled in a bitter dispute over the Brokholes inheritance. Joan’s sister and coheir Margery had never succeeded to her share of the inheritance, for she had died at a relatively young age. Her heir was John, her son by her husband John Sumpter* of Colchester, but he died, still a minor, in July 1420. Young John’s sisters Christine and Ellen survived him, but Joan asserted that they were illegitimate and laid claim to his moiety of the Brokholes lands. Eventually a much delayed inquisition post mortem held in Essex declared that Christine and Ellen were the boy’s rightful heirs but Joan never forsook her claim to the whole inheritance.
By about 1450, Robert Arneburgh was asserting that his late wife had willed the sale of all her fee simple lands, and that she had directed that he might buy them at a discounted price. In doing so, he was contradicting the settlement of 1443, although it is possible that Joan had overturned this arrangement in her will, which has not survived. Whatever the case, Reynold was prepared to go along with his uncle’s claim, since he tried to bully Robert into surrendering the lands to him. He brought considerable pressure to bear on Robert, getting a ‘juge of this londe’ to speak to him on his behalf. Robert refused to give way and incurred the displeasure of both Reynold and the judge as a result.
By the 1450s, Reynold was residing at Hemingford Grey,
Possibly Reynold was never reconciled with Robert Arneburgh, who must have been dead when the wider dispute over the Brokholes inheritance finally ended. In spite of quarrelling with his uncle, Reynold had continued to uphold the Arneburghs’ cause against John Sumpter’s surviving daughter Ellen and her second husband Ralph Holt of Lancashire. Following a Chancery suit on the part of the Holts, the dispute went to arbitration. The four arbitrators, Robert Wyllenhale and Thomas Umfray*, acting for Reynold and another of Joan Arneburgh’s feoffees, Sir Philip Thornbury*, on the one hand, and Thomas Urswyk II* and Guy Fairfax, representing the Holts on the other, made their award on 21 July 1453. They assigned the complete inheritance to Ellen, by now the sole surviving representative of the Brokholes line. Reynold and Thornbury were to have only an interest in Joan Arneburgh’s Suffolk lands, which had never been part of the Brokholes estate.
Soon after this setback, Reynold was caught up in a quarrel with Thomas Burgoyne* and his wife Alice. In early 1455, he was the leading defendant in two suits that the Burgoynes brought in the court of common pleas. In the first, he and his co-defendants, mainly husbandmen or labourers, stood accused of having broken into the Burgoynes’ close at Impington, Cambridgeshire, on the previous 24 Sept.; in the second, they stood charged with assaulting Alice there on the same day.
There is little information about Reynold’s later years. He was appointed a j.p. in Huntingdonshire in June 1460 but was removed shortly after the accession of Edward IV. He disappears from view after December 1461, when he gained admission to repasts at Lincoln’s Inn for the next seven years,
