Etymology of Trehiou

What does the name Trehiou mean?

Trehiou is one of the many new names that came to England following the Norman Conquest of 1066. The Trehiou family lived in Cornwall, at the village of Tewardevi, from which their name is derived.

Early Origins of the Trehiou family

The surname Trehiou was first found in Cornwall where they held a family seat from early times. There is also some evidence to believe that they were descended from Richard of Trethewey, a Norman knight, who held this village from the Count of Mortaine during the Norman occupation as recorded in the Domesday Book taken in 1086.

Trehiou Spelling Variations

Anglo-Norman names are characterized by a multitude of spelling variations. When the Normans became the ruling people of England in the 11th century, they introduced a new language into a society where the main languages of Old and later Middle English had no definite spelling rules. These languages were more often spoken than written, so they blended freely with one another. Contributing to this mixing of tongues was the fact that medieval scribes spelled words according to sound, ensuring that a person's name would appear differently in nearly every document in which it was recorded. The name has been spelled Trethewey, Trethewy, Trethevy, Threthaway, Treadaway and many more.

Trehiou migration to the United States +

For many English families, the political and religious disarray that plagued their homeland made the frontiers of the New World an attractive prospect. Thousands migrated, aboard cramped disease-ridden ships. They arrived sick, poor, and hungry, but were welcomed in many cases with far greater opportunity than at home in England. Many of these hardy settlers went on to make important contributions to the emerging nations in which they landed. Among early immigrants bearing the name Trehiou or a variant listed above were:
