The manor of Trevose, that is, the town in the valley, from its
principal mansion so called, where are the ruins of a very large
house, as having been formerly a seat of the Killigrews, and
particularly in J. Norden’s time of Sir William Killigrew, to which
family, together with other lands adjoining, I suppose it came by
their marriage with the daughter and heir of Arwinick. This property
was sold to Sir Nicholas Slanning of Marystow in Devonshire, who I
believe made this place his residence, while he was Governor of
Pendinas Castle. This was the famous Sir Nicholas Slanning, so much
cried up for his valour, who had a chief command in the King’s army,
and was killed before Bristol in July 1643. He left a son of the same
name, then an infant, who was made a Baronet by King Charles II. in
1662, as he had been before that one of the Knights of the Bath at his
Majesty’s Coronation; which Sir Nicholas Slanning gave for his arms,
Argent, two pales ingrailed Gules, over all a bend Azure, charged with
three griffin’s heads erased Or.
This gentleman sold Trerose to Brian Rogers of Falmouth, merchant, who
left by his wife, the daughter of John Tregeagle of Trevorden, Esq.
one only son, Peter Rogers, Esq. who dying under age, the estate was
sold to pay his father’s debts, under the authority of an Act of
Parliament, to James Kempe of Penryn, Esq. who settled it on his
second son James Kempe; but he died in his father’s lifetime; and,
therefore, on his father’s death, in 1711, it fell to his son John
Kempe, who marrying Mary the daughter of Joshua Ratcliff of Francklyn
in Devonshire, Esq. died in May 1714, leaving an only daughter, who
died soon afterwards. The manor ultimately devolved to Nicholas Kempe
of Rosteage, Esq. who is the present lord thereof. Mr. Rogers gave for
his arms, as deriving himself from the Rogerses of Cannington in
Somersetshire, Argent, a chevron between three bucks courant Sable,
attired Or.
The advowson of the parish was appendant to this manor, but has been
severed therefrom, and now belongs to John Peters, Esq. of Harlyn.
In this parish is also Penwarne. This has been for many generations
the seat of an ancient family of the same name, where they have
flourished, being Justices of the Peace, and Members of Parliament;
they began, however, to decline about the middle of Queen Elizabeth’s
time, till Peter Penwarne, Esq. parted with almost the whole of his
landed property, except the barton. The present gentleman married
Joan, the daughter of Thomas Taylder of St. Mabe, gent.; his father
Robert the daughter and heir of Peter Spry of Tregony, merchant.
Mr. Peter Penwarne died this present year (1732), leaving two sons,
Thomas and John. The arms of Penwarne are, Sable, a chevron between
three fleurs-de-lis Or.
