Trefusis family

The Trefusis family of Cornwall (anciently "de Trefusis") continue in 2018 as lords of the manor of Trefusis, near Flushing in the parish of Mylor, Cornwall, from which they took their surname at some time before the 13th century.
In 1794 Robert George William Trefusis (1764–1797) of Trefusis, the senior representative of the family, successfully claimed the peerage title Baron Clinton following the death in 1791 without progeny of his grandfather's 3rd cousin George Walpole, 3rd Earl of Orford, 16th Baron Clinton (1730–1791), and thus became the 17th Baron Clinton. Both Walpole and Trefusis were descended from the marriage of Robert Rolle (c. 1622 – 1660) of Heanton Satchville, Petrockstowe, Devon, and Lady Arabella Clinton, the younger daughter of Theophilus Clinton, 4th Earl of Lincoln, 12th Baron Clinton (died 1667).
The senior line of the Trefusis family died out in the male line in 1957 on the death of Charles John Robert Hepburn-Stuart-Forbes-Trefusis, 21st Baron Clinton (1863–1957), who left two daughters and co-heiresses to the barony, which went into abeyance, but being an ancient one created by writ, is able to descend via female lines.
The abeyancy was terminated in 1965 when the title Baron Clinton was claimed by Gerard Nevile Mark Fane-Trefusis (born 1934), a descendant in a junior line of Thomas Fane, 8th Earl of Westmorland (1701–1771), and the grandson of the 21st Baron's eldest daughter, who in 1958 had assumed by deed poll the additional surname of Trefusis, and thus became the 22nd Baron Clinton and is living in 2015.
As he inherited the vast Devonshire estates (mostly formerly belonging to the Rolle family) of the 21st Baron, who "held sway over the largest estate Devon had ever seen", (now managed by his Clinton Devon Estates company), the Cornwall estates including Trefusis descended to Major Hon. Henry Walter Hepburn-Stuart-Forbes-Trefusis of the Scots Guards, the second son of Charles Henry Rolle Hepburn-Stuart-Forbes-Trefusis, 20th Baron Clinton (1834–1904), and in 2015 the occupant of the manor house of Trefusis is the Major's grandson Nicholas John Trefusis (born 1943), Lieutenant-Commander Royal Navy, a Justice of the Peace for Cornwall and a Deputy Lieutenant for that county.
