He was unmarried and childless at the time of his death. The manor and Castle of
Tiverton and his other numerous estates devolved to his distant cousins, descended from the four sisters of his great-grandfather
Edward Courtenay, 1st Earl of Devon (d.1509), all children of Sir
Hugh Courtenay (d.1471) of
Boconnoc in Cornwall and his wife, Margaret Carminow. These four sisters were as follows: • Elizabeth Courtenay, wife of John Trethurffe of
Trethurffe in the parish of
Ladock, Cornwall. • Maud Courtenay, wife of John Arundell of Talvern • Isabel/Elizabeth Courtenay, wife of William Mohun of
Hall in the parish of
Lanteglos-by-Fowey in Cornwall, a descendant of John Mohun (d.1322) of
Dunster Castle in Somerset,
feudal baron of Dunster by his wife Anne Tiptoft. In 1628 her descendant
John Mohun (1595–1641) was created by King Charles I
Baron Mohun of Okehampton, his ancestor having inherited as his share
Okehampton Castle and remnants of the
feudal barony of Okehampton, one of the earliest possessions of the Courtenays. The Mohuns' held the manor of
Boconnoc not (as might be expected) as a share of the Courtenay inheritance, but by lease from the Russell
Earl of Bedford. • Florence Courtenay, wife of John Trelawny Thus the Courtenay estates were divided into four parts. • Reginald Mohun (1507/8-67) of Hall in the parish of
Lanteglos-by-Fowey in Cornwall, who inherited
Okehampton Castle and Boconnoc. His descendant was
John Mohun, 1st Baron Mohun of Okehampton (1595–1641) who was elevated to the peerage by King Charles I as Baron Mohun of Okehampton, in recognition of his ancestor having inherited Okehampton Castle as his share of the Courtenay inheritance. • Margaret Buller; • John Vivian; • John Trelawny;
The Courtenay Faggot (d.1511), of
Tiverton Castle, above the south porch of St Peter's Church, Tiverton, next to the Castle. Part of the Greenway Chapel, built in 1517 by the wealthy Tiverton merchant
John Greenway (d.1529), whose initials are seen above the Courtenay arms. Above and between two White Roses of York appears the very rarely seen
heraldic badge of the Courtenays:
A falcon rising holding in its claws a bundle of sticks. This is possibly a reference to the "Courtenay
Faggot" described by Richard Carew (d.1620) in his
Survey of Cornwall. The imagery is however reminiscent of the "Eagle of Jupiter" holding in his claws a thunderbolt, the emblem of that deity, as commonly seen on ancient Greek and Roman coins The
Courtenay Faggot was a mysterious naturally misshapen piece of wood split at the ends into four sticks, one of which again split into two, supposedly kept as a valued possession by the Courtenay Earls of Devon. It was later interpreted as an omen of the end of the line of Courtenay Earls of Devon via four heiresses. It was seen by the Cornish historian
Richard Carew (d.1620) when visiting Hall, then the dower house of Margaret Reskimer, the widow of Sir William Mohun (d.1588), MP, of Hall, the great-grandson of Elizabeth Courtenay, who described it in his
Survey of Cornwall as follows: :"A farre truer foretoken touching the Earle of Devon's progeny I have seen at this place of Hall, to wit, a kind of
faggot, whose age and painting approveth the credited tradition that it was carefully preserved by those noble men. But whether upon that prescience or no, there mine author fails me. This faggot being all one peece of wood, and that naturally growen, is wrapped about the middle part with a bond and parted at the ends into foure sticks, one of which is againe sub-divided into other twayne. And in semblable maner the last Erle's inheritance accrued unto 4 Cornish gent(lemen): Mohun, Trelawny, Arundell of Talverne and Trethurffe. And Trethurffe's portion Courtenay of
Ladocke and Vivian do enjoy, as descended from his two daughters and heires". ==Portraits==
