Cornish surnames are an incredibly intriguing subgroup of British Isles onomastics, with roots in the Cornish language, a Brythonic Celtic tongue closely related to Welsh and Breton, and layers of influence from Old English, Norman French, and English administrative history.
Until recently, Cornwall was very isolated, which contributed to the preservation of many distinctive toponymic, occupational, and descriptive surnames. Tre- (“homestead”), Pol- (“pool”), Pen- (“head, hill”), Ros- (“moor”), and Lan- (“church”) are only a few examples of names that are derived directly from the terrain, nature, and Celtic personal names. In recent years, interest in surname etymology has increased as a result of the resurgence of the Cornish language and culture.
History of Cornish surnamesHistory of Cornish surnames
Cornish surnames were not used until the Middle Ages and were not generally fixed until about 1600. At first they were used to help keep track of those with common given names. With the growing church and civil bureaucracy, names related to one's home or farm, one's father, one's job, or a personal characteristic became attached to a person and were passed to one's children. There are also a few names, like Bowden/Bawden from Baudouin/Baudin/Boudin, which may have been taken from the Norman French conquerors of 1066 as well as English names that made their way west to Cornwall. Long before Cornish surnames became inherited, they frequently served as place indicators, such as in Tre- fields or Pol- pools.
Cornish surnames naming conventionsCornish surnames naming conventions

Cornish surnames are derived from a number of sources. Many are from patronymics, taken from one's father's (and occasionally one's mother's) given name. These names aren't as easy to spot as one might imagine as they are not as straight forward as, say, a Scandinavian Knutson or Svenson. Many of the Cornish patronymics take the “root” given name and give it a twist, such as Robert is the origin of Hob or Dob prefixes, Roger morphs into Hodge and Dodge, Kitto is from Christopher, and Sandow derives from Alexander. To sort out the names associated with jobs, one has to do a little research and learn some Cornish. Angove is the Cornish word for a blacksmith, Tyack, a farmer, and Tremethyk, a homestead where a doctor lives. Other names were derived from personal characteristics of the original holder of the name such as Coad, old, or Gwyn, white.
Particularly during the Middle Ages, when farming communities and monastic foundations were called and passed down, many Cornish surnames have Christian and Celtic origins.
There are a few prefixes that make Cornish surnames easily identifieable. The oft recited: “By tre, pol, and pen, ye shall know all Cornishmen” or the later variation, “By your tre, ros, pol, and pen, ye shall know most Cornishmen,” covers many, but not all Cornish surnames. The names that begin with these prefixes borrow directly from the Cornish language and represent:
- Tre: An abbreviation of treveth, meaning a farm or homestead. Examples: Tremain, Trelawnny, Trevelyan, Treglown, Trevithick, and dozens more
- Ros: A prefix denoting higher ground, either a moor or a headland that juts into the water Examples: Rosewarne, Roskilly, Roseveare(spelled several ways), Rosdew, Rosemergy, etc.
- Pol: A pool, pit, or perhaps originally, also a cove. Examples: Poldark, Polkinhorne Polglase, Pollard, Polwhele, Polwin, etc.
- Pen: An end of something. Examples: Penrose, Penhaligon, Pendarvis, Penhallow, Pengelly, Pentreath, etc.

In addition to the prefixes found in the rhyme, other common prefixes include:
- Lan, usually referring to a church, as in Landry, Lanfear, Lansallos, Lanyon, and Lander
- Bos/Bod, referring to a home, as is Boscawen, Boswarva, and Bosense
- Car, referring to a round fortification, including Carkeek, Carveth, Carlyon, and Cardew
- Chy/Che, also a house or cottage, as in Chenoweth, Chegwin, Chegwidden, and Chellew
- Nan, denoting a valley, as in Nance, Nancekivell, Nanscawen, Nankervis, and Nancarrow
The second part of these types of Cornish names also has a meaning, of course. So Treglown for example, becomes Homestead by the Hedged Pond and Chenoweth, a New House. For a surname beginning with Tre, it may be possible to find the site of the Cornish farm or homestead once owned or inhabited by the original bearers of the surname, as many of the place names remain today.
It is important to take into account that as the Cornish language was not standardized until 2008, there is no unified way to spell the same surname, which means that Treglohan can be Treglown, Tregloan, Treglawn, or Treglone. Sometimes two or more spellings for the same surname can appear on the same document. Siblings, parents, and cousins may be associated with names sporting variant spellings.
Types of Cornish surnamesTypes of Cornish surnames

- Penrose – Pen (head/hill) + ros (moor): “hill on the moor”
- Polkinghorne – Pol (pool) + personal name or location suffix
- Tregenza – “farm of Kenza”
- Trevelyan – “farm of Elyan”
- Penhaligon – “end of the willows”
- Roskelly – ros (moor) + kelly (grove): “moor grove”
- Trethewey – “farm of the thieves” or “windy farm”
- Pendarvis – “end of the river valley”
- Lanyon – from lan (church site) + yon: “sacred enclosure”
