The history of the last name Curnow

The surname Curnow is believed to have originated in Cornwall, England, a region known for its distinct Celtic heritage and linguistic traditions. It is thought to derive from the Cornish language, which was widely spoken in the area until the late 18th century.

One theory suggests that Curnow is derived from the Cornish words "ker" meaning "home" or "settlement" and "noe" meaning "new" or "fresh". This combination would translate to "new home" or "new settlement", possibly indicating that the name was originally given to someone who established a new homestead or village.

Another interpretation proposes that Curnow stems from the Cornish words "corn" meaning "horn" and "now" meaning "valley" or "creek". In this case, the name could have referred to a particular geographical feature, such as a horn-shaped valley or a settlement situated near a creek with a distinctive bend resembling a horn.

The earliest known record of the surname Curnow dates back to the late 16th century, appearing in various Cornish parish records and legal documents from that time period. One notable example is found in the Protestation Returns of 1641-1642, a series of documents recording the pledges of allegiance made by English subjects during the early stages of the English Civil War.

Over the centuries, the surname has undergone various spelling variations, including Cornow, Kernow, and Kernough, reflecting the influence of regional dialects and the gradual transition from Cornish to English as the dominant language in the area.

Among the notable individuals bearing the Curnow surname throughout history are:

  1. William Curnow (1799-1865), a Cornish poet and writer known for his works in the Cornish language, such as "The Ancient Cornish Drama" and "The Curn Vilien".

  2. John Curnow (1813-1897), a prominent Cornish mining engineer and industrialist who played a significant role in the development of the Cornish mining industry during the 19th century.

  3. Erica Curnow (1855-1936), a British painter and illustrator known for her depictions of Cornish landscapes and rural scenes.

  4. Thomas Curnow (1868-1945), a Cornish-born Australian politician who served as a member of the Australian House of Representatives for the electorate of Wilmot from 1922 to 1931.

  5. William Curnow (1892-1986), an English composer and conductor who made significant contributions to the brass band repertoire, including the famous march "Eb Tonic".

While the surname Curnow is predominantly associated with Cornwall and the surrounding regions, it has since spread across various parts of the United Kingdom and beyond, carried by generations of individuals with Cornish ancestry or those who migrated from the region over the centuries.
