The Atlantic Ocean to the north and west and the English Channel to the south borders Cornwall, the homeland to the Trewen family name. Even though the usage of surnames was common during the Middle Ages, all English people were known only by a single name in early times. The manner in which hereditary surnames arose is interesting. Local surnames are derived from where the original bearer lived, was born, or held land. The Trewen family originally lived in Cornwall, at the manor of Trevanion.

Early Origins of the Trewen family

The surname Trewen was first found in Cornwall where they held a family seat at Trevanion. While the first records of the surname were from this area, we must look into Wales to understand the meaning of the word "trevanion, " for it is there that the word translates to "the meeting of streams."

Trewen Spelling Variations

Cornish surnames are characterized by a multitude of spelling variations. The frequent changes in surnames are due to the fact that the Old and Middle English languages lacked definite spelling rules. The official court languages, which were Latin and French, were also influential on the spelling of a surname. Since the spelling of surnames was rarely consistent in medieval times, and scribes and church officials recorded names as they sounded rather than adhering to any specific spelling rules, it was common to find the same individual referred to with different spellings of their surname in the ancient chronicles. Moreover, a large number of foreign names were brought into England, which accelerated and accentuated the alterations to the spelling of various surnames. Lastly, spelling variations often resulted from the linguistic differences between the people of Cornwall and the rest of England. The Cornish spoke a unique Brythonic Celtic language which was first recorded in written documents during the 10th century. However, they became increasingly Anglicized, and Cornish became extinct as a spoken language in 1777, although it has been revived by Cornish patriots in the modern era. The name has been spelled Trevanion, Treavanion and others.
