A lawyer like his father, Roger received his training at the Middle Temple. Of obscure origins, John Kemys enjoyed a successful professional career, although his chief means of advancement was his extremely advantageous match with Roger’s mother. John’s wife, Margaret Russell, was the widow of Sir Gilbert Denys† of Siston and the daughter and eventual coheir of Sir Maurice Russell†, a substantial landowner in south-west and southern England. John married in or shortly after December 1422, so it is likely that Roger had only recently attained his majority when named as one of the elder man’s feoffees in September 1444.
It is unlikely that Roger always lived at Siston, for he was referred to as ‘of Bedminster’ on one occasion in 1453-4.
Some years later, John Kemys founded a chantry in the Bristol parish church of St. Philip and St. Jacob, and in the spring of 1467 Roger was party to a conveyance by which his father endowed his foundation with lands at King’s Barton near Gloucester.
Among the other lawyers responsible for the Haddon-Carew award was William Mauncell of Bristol, whose widow Agnes had become Roger’s second wife by the early 1470s. At some point in 1471-2, Humphrey Forster† and his wife Sibyl sued Kemys and Agnes in the Chancery. In their bill, the Forsters referred to an earlier quarrel (concerning 31 messuages and a rent of 24s. p.a. in Bristol) between Sibyl and her former husband Robert Poyntz on the one hand, and Agnes and her own previous spouse, William Mauncell, on the other. According to the Forsters, a panel of arbiters had awarded title to Agnes and Mauncell, while at the same time directing that Sibyl and Poyntz should receive a rent of £15 p.a. from the same properties. The Forsters complained that Kemys and Agnes were now refusing to pay this annuity and that Poyntz’s executor Humphrey Cuderington had connived with Roger to preclude Sibyl’s rightful claim to it.
Even if Roger found much of his work as a lawyer in Bristol, he must also have frequently visited Westminster and his inn of court in pursuit of his legal duties. Among his acquaintances was the cordwainer Henry Williams, a parishioner of St. Clement Danes near the Middle Temple. In June 1450 he became one of Henry’s trustees, along with none other than (Sir) John Fortescue*, chief justice of King’s bench, and the Chancery clerk, William Normanton.
Aside from York, it is also difficult to find any conclusive evidence linking Roger with other lords. As a deputy justiciar of South Wales in 1455, he was subordinate to John, Lord Beauchamp of Powick, then the nominal justiciar of that lordship. The extent of his dealings with Powick is unknown and he perhaps associated more regularly with another peer, James, Lord Berkeley, and his family. In January 1461, James’s younger son Maurice Berkeley conveyed away the Gloucestershire manor of Little Marshfield to him, and Richard Arthur – presumably one of Kemys’s in-laws – married Maurice’s sister Alice in about 1465. Roger did not acquire Little Marshfield on a permanent basis, for he re-conveyed it to Berkeley, who may have mortgaged it to him, at the beginning of 1470.
Whatever his ties with the nobility, Kemys must have associated more often with his fellow gentry, for whom he was sometimes a witness and trustee, roles he also performed for others lower down the social scale.
After the mid 1470s, Kemys ceased to serve as an ad hoc commissioner, although he retained his position as a working j.p. in Gloucestershire. He finally lost his place on the commission of the peace in the spring of 1481, possibly through ill health since he suffered a serious mental breakdown just a few months later. An inquisition held by the Gloucestershire escheator in February 1482 revealed that he had suffered from a state of lunacy, albeit with occasional lucid intervals, since the previous 1 Aug. In response to this finding, the Crown granted the custody of his person and estates to his son Arthur in April 1482. Roger survived until 3 Jan. 1485, but another year passed before an inquisition post mortem was held for him in Gloucestershire. His heir was his eight-year old grandson, John Kemys, son of his late eldest son of the same name. The boy inherited a small estate in Gloucestershire, comprising two third shares of the manor of Oldbury acquired in the 1450s and 1460s, a manor or messuage at Wick and messuages in Stapleton, Dyrham, Hinton and Barton Regis. According to the inquisition evidences, these lands produced an income of no more than about £15 p.a., although the Denys manor of Siston, which had passed to Roger following his father’s death in mid 1476, was worth at least another £18 p.a.
