Trethewy

 

About the study

The Trethewy One-Name study was started by the late Alan Kent, who set up the Trethewy Society in 1993.

This is a worldwide study of the surname and variants, coming together as the Trethewy Society. The society is now run by Raymond Trethewey and Sally Whiffing, with members from England, Australia, Canada, and the USA.

The aims of the Trethewy society are:-

  • Share information and research into the Trethewy Family
  • to document the trees of all Trethewy name-bearers
  • to verify those trees through DNA testing where possible
  • to gain a better understanding of the early Trethewys and how the different branches may be connected

Variant names

Trethaway, Tretheway, Trethewey, Trethewie

Name origin

‘Dewi’ or ‘David’s homestead’ is the most likely origin. Some of the variants may be explained as the ‘homestead near the grave’ as in Trethevy Quoit and the Tintagel place name. It has been suggested that ‘homestead above/near the water’ may be another possibility. A couple of Trethewy place name locations would fit this.

The Anglo Saxon Chronicle first recorded the place name of ‘Trethewey’ ‘tref daewig’ in St Martin in Meneage in 977 AD. There are now six places in Cornwall called Trethewey:

  • St Neot parish, near Treverbyn and close to the River Fowey
  • St Ervan, near Padstow
  • Ruanlanihorne
  • Germoe
  • St Levan
  • St Martin in Meneage

There are also similar place names such as Trethevey and examples can be found in:

  • The parish of Lanlivery (close to Lostwithiel)
  • St Mabyn (adjacent to Egloshayle )
  • Trethevy Manor (near Tintagel)
  • Lewannick, near Launceston

Surnames didn’t become established until the mid-1300’s. It is possible that names changed as people moved residences. Documentation dating back to the early 1200’s refers to people carrying the name De Tredewi and De Trethewy. One of the earliest references is a deed relating to the Priory of St Andrews at Tywardreth.  This records a grant of Odo de Treverbin, where one of the witnesses was Johanne de Tredeway.

Further early references relate to:

  • 1278 John De Trethewy held lands in Penpell, Trethewy and Polharmon
  • 1279 Henry De Trethewy, accounting for Foweymore Stannary Courts
  • 1311 a John Trethewy was a servant of Treverbyn, aged 54
  • 1325 Henry De Trethewy, Mayor of Bodmin
  • 1333 Henry Trethewy appointed keeper of Launceston Castle and sheriff of Cornwall. In 1334 he is quoted as ‘son of John, son of John’.
  • 1354 Robert Trethewy, fellow and Rector of Exeter College, Oxford
  • 1356 Henry De Trethewy
  • 1361 Robert De Trethewy, Priest of East Allington (also referred to as alias Boscaveye later incumbent at Phillack in 1380)
  • 1376 John De Trethewy, Mayor of Launceston and also mentioned regarding an agreement at Pelynt in 1378.

History of the name

It is possible that there were several different Trethewy families in the County or that these were branches of a larger inter connected Trethewy family.  The coat of arms with goats and engrailed chevron seems to add weight to this.

A number of Trethewys served as Members of Parliament and Coroners:

1325 - Henry was MP for Bodmin

1382 - Phillip was MP for Liskeard, and also Launceston

1421 - Richard was MP for Liskeard in

1429 and again in 1435 - William was MP for Liskeard

1441- William (of Keverall near Looe) was Coroner 

1455 - Robert was MP for Liskeard

1467 - Thomas was MP for Cornwall and also Coroner  

The early records suggest a cluster of Trethewys around the Lostwithiel, Liskeard and Looe areas.  These are associated with the accounting of the Tin Stannaries and the earldom and later Duchy of Cornwall. They were prominent landowning families, serving as MP’s, Coroners and duties for the crown.  Research shows tantalising connections between these families.  It is inferred that John Trethewy of Treverbyn was William Trethewy’s father and Thomas Trethewy’s grandfather.

J L Vivian’s ‘Visitations of the County of Cornwall’ show a direct link from John and Henry Trethewy to Thomas the Coroner, however the lineage would seem to be more complex.

Despite the earlier uncertainties, recent Trethewys would seem to derive from Thomas Trethewy MP and Coroner for the County in 1467. He was in dispute with the Vivian family of Trelowarren raiding the estate killing a servant and later outlawed. He was later pardoned but set up residence at St Stephen in Brannell in 1472.  The family held seats at Treneague, Trevear, Tregargus and Meledor. Research would suggest that present day Trethewys may have originated from this branch.

Other notable Trethewys:

  • John ‘Jack’ Trethewey of St Stephens was Secretary to Lord Hopton and a consort of Charles II
  • His brother, Lewis Trethewey, was Receiver General and also a consort of Charles II
  • William Griffith Trethewey (1865-1926). A mining engineer whose discovery of the Trethewey and Coniagas mines in Cobalt, Canada, led to him becoming a millionaire. He owned the Trethewey Model Farm in Toronto, which by 1910 had become Trethewey Airfield, hosting the first Toronto Airshow. He was also very interested in his Trethewey ancestry.
  • William Thomas Trethewey (1892-1956). New Zealand born sculptor
  • Natasha Trethewey (born 1966). Pulitzer-winning Afro-American poet
  • In 1991 Flight Sergeant Paul Leslie Trethewey was awarded the Air Force Medal for helping to save the lives of 16 crew of the ‘Kartli’ off Prestwick.
  • In 2015 Captain Tim Tretheway ‘stepped ashore’ after more than 28 years volunteering with the Mercy Ships - Hospital Ships helping developing countries
