Trethewy is one of the names that was brought to England in the wave of migration following the Norman Conquest of 1066. The Trethewy family lived in Cornwall, at the village of Tewardevi, from which their name is derived.

Early Origins of the Trethewy family

The surname Trethewy was first found in Cornwall where they held a family seat from early times.

Trethewy Spelling Variations

Before the advent of the printing press and the first dictionaries, the English language was not standardized. Sound was what guided spelling in the Middle Ages, so one person's name was often recorded under several variations during a single lifetime. Spelling variations were common, even among the names of the most literate people. Known variations of the Trethewy family name include Trethewey, Trethewy, Trethevy, Threthaway, Treadaway and many more.
