Bello Prato, Trevanion, Trewartheneck and Treaigo of Cornwal

J. L. Vivian in his published pedigree of the Trevanion family shows
the original pedigree of the 1620 heraldic visitation with additions
thereto. The original visitation pedigree starts with a Sir John
Trevanion married to a Jone, daughter and heiress of Stephen de Ballo
Prato, and their having two sons:
1. Robert, who married the daughter and heiress of "Le Archdecon",
and
2. Sir John Trevanion, ob sine prole, marr. a daughter of Richard le
Sergiaux.

Robert is then shown as the father of a second Robert and the grandson
of a third, i.e. no other John Trevanions appear in the next two
generations of the family.
To this visitation pedigree Vivian has added Joan, married to Stephen
Trewartheneck, as a daughter of the original John by Joan de Bello
Prato. This is because the pedigrees of both Spry of Place and
Boscawen of Tregothnan have the following descent:

Gen 1. Stephen Trewartheneck, marr. Jane or Joan, daughter of John
Trevanion
Gen 2. Jane Trewartheneck, marr. John Treiago
Gen.3. Stephen Treiago, marr. Alice Cheynduit.

It seems to me though that there is a major chronological problem here
once one amalgamates the above data, as Vivian did.

A published abstract of an Inquisition Post Mortem dated 21 April, 2
Edward II for Stephen de Bello Prato has his mother Joan still living
and holding land in dower, and his heir as his son Ralph, then aged 9.
"Isabella who was wife of Stephen de Bello Prato" is mentioned in
rolls dated 9 Edward II, and a writ of diem clausit extremum was
issued concerning her in 19 Edward II.

In 1329 a William de Trevaygon sold the manor of Nansladron in St Ewe
to Odo de Nansladron and Idonia his wife, the daughter of Robert
Trevanion and his wife, a daughter of the Archdekne family. William
also granted that the reversion held by him on some other lands,
including land and houses held for life by John de Trevaygnon at
Penhale and St Goron, should also go to the Nansladrons.

In 1335 Stephen Trewartheneck sold the Cornish manor of Fentongollan
to John and Jane Treiago, with remainder to Stephen Treiago and Alice
his wife. (Hence John and Jane's son and ultimate heir was married by
that date) In 1311 John and Jane Treiago bought land at nearby Merther
parish.

John Treiago is well known from Cornish records of that time, being MP
for Truro in 1304, a commissioner to investigate the behaviour of tax
collectors in Devon in 1318, sheriff of Cornwall in 1323 and 1325, and
he represented the shire in 1306, 1312, 1318, 1328 and 1340. He was
evidently dead by 1346, as it is recorded that Fentongollan, having
been formerly held by Johannes de Trejagu, was then held by the Black
Prince.

In an inquisition dated January 1318/19 concerning the proof of age of
a member of the Bloyou family of Ludgvan in Cornwall, one of the
witnesses is a John Treyagu, knt. aged 40, who mentions in his
testimony that he was at the Bloyou manor of Tregawel in September
1296 when the Bloyou heir was born, and that he himself had a son John
who broke his leg on the same day.

On Vivian's reconstruction Joan Treiago, nee Trewartheneck, is the
great-granddaughter of Stephen, and as there seems to have been only
the one Stephen de Bello Prato it follows that she must have been the
grandniece of the said Ralph de Bello Prato who is shown as Stephen's
heir in the IPM of 1309.
The identical relationship to Ralph applies for Joan's supposed first
cousin Idonia Nansladron, nee Trevanion.

However given the above dates for Idonia and her husband Odo, and for
Joan's husband John Treaigo and their sons and daughter-in-law, how
can this be??

According to the fine, Idonia was married by 1329 at the very latest,
but this is only 30 years after the birth of Ralph. How then can Ralph
be her granduncle? Even if Joan Trevanion, nee Bello Prato, was
possibly somewhat older than Ralph, thus allowing for more years
between the generations on Idonia's line, the picture is worsened when
the Treiagos are then factored in as well. John Treiago according to
his own testimony was born c. 1278, and this seems to fit in well with
other details concerning him and his immediate family, but this means
that he was born 21 years earlier than Ralph his supposed granduncle-
in-law, and Ralph is even younger than John and Jane's son John
junior, Ralph's supposed great-grandnephew! In addition we would have
no more than 36 years at the most between the birth of Ralph and the
marriage of his other great-grandnephew Stephen Treiago.

Something has got to be wrong somewhere. It seems to me that either
the Trevanion visitation pedigree is wrong and the mother of Idonia's
father Robert Trevanion was not a daughter of Stephen de Bello Prato
at all, and/or else Vivian is wrong in placing Joan Trewartheneck, nee
Trevanion, as a sister to this Robert. I see James Whetter has John
Trevanion marrying twice, firstly to Joanna daughter of Stephen de
Beaupre (i.e. Stephen de Bello Prato) and secondly to Isabel daughter
of William Fitz Ivo, but this does not resolve the above problem as
the Bello Prato marriage comes first.

Can anyone shed any light on the above?

PS: Incidentally property at Trenewith and Trewithgy held by Stephen
in 1303 appears in the lands of a John de Bello Prato in 1346,
suggesting that the visitations were at least incorrect in calling
Joan de Bello Prato Stephen's "heiress"; presumably therefore Ralph
survived to adulthood and had children.
