The Nanfans were an ancient family from western Cornwall with long established traditions of parliamentary service. Both James’s father and grandfather had represented Cornish boroughs in the Commons: Henry Nanfan† sat for Lostwithiel in 1361 and secured a double election at Helston and Launceston in 1363, while his son Thomas was returned for Helston in 1377.
By early 1418, Nanfan had married Margaret, one of the two daughters and coheiresses of John Megre, a tin merchant normally resident in London, but with property in Penryn, Truro and Kenwyn.
There is nothing to suggest that Nanfan took an early interest in parliamentary affairs on account of family tradition, for it was only after his own return for Truro in 1426 that he is known to have attended the Cornish shire elections, and his subsequent regular appearances on these occasions may have owed more to his official duties in the county court as a coroner than to any personal interest in the representation of his shire. Certainly, he seems to have owed his own single election for Truro to his local credentials, for at least one of his sureties, William Penalewy†, was a local man.
The coroners’ duties were often onerous, and it is possible that Nanfan himself procured the royal writ which ordered his dismissal on grounds of ill health in July 1433. The reverberations of his official conduct nevertheless continued to haunt him for some time and as late as the autumn of 1445 a royal writ of certiorari ordered an inquiry into an inquest into the murder of one Hervy Rawlyn held by Nanfan in May 1432. Nanfan was forced to defend his conduct of the inquiry in the court of King’s bench, but was subsequently fined 13s. 4d. when the justices found fault with it.
A few years earlier, James had been among a group of men headed by his more important kinsman John Nanfan* who were accused by William Clerk alias Tanner, second husband of Philippa Bodrugan, of having conspired to secure his wrongful indictment and imprisonment for supposedly purloining some of the deceased Sir William Bodrugan’s muniments, which rightfully pertained (along with custody of the Bodrugan estates) to John Nanfan’s master, Henry Beauchamp, duke of Warwick.
By this date it must have been increasingly clear that Nanfan was unlikely to father a son, and he began to take a keen interest in his grandson, John Trenewith*, the son of his elder daughter. He headed the witnesses at Trenewith’s proof of age in September 1449, and although he was rather vague about his own age, he remembered clearly seeing the boy being lifted out of the font of the church of St. Michael Penkivel almost 23 years earlier.
The exact date of Nanfan’s death has not been established, but it occurred at some point before 1470, by which date his holdings in Beauripper, Penpons, Redallen and elsewhere were in the Trenewith’s hands. Nanfan’s younger daughter, Beatrice, had remained in the care of her maternal grandmother, Emma Megre, after her mother’s death, and at the age of 15 had married the Somerset esquire Hugh Malet. They had several children, none of whom survived their mother, who was herself dead by the late 1460s.
