Trethewey History, Family Crest & Coats of Arms

Trethewey is a name that came to England in the 11th century wave of migration that was set off by the Norman Conquest of 1066. The Trethewey family lived in Cornwall, at the village of Tewardevi, from which their name is derived.

Early Origins of the Trethewey family

The surname Trethewey 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.

Trethewey Spelling Variations

The English language only became standardized in the last few centuries. For that reason, spelling variations are common among many Anglo-Norman names. The shape of the English language was frequently changed with the introduction of elements of Norman French, Latin, and other European languages; even the spelling of literate people's names were subsequently modified. Trethewey has been recorded under many different variations, including Trethewey, Trethewy, Trethevy, Threthaway, Treadaway and many more.

United States Trethewey migration to the United States +

To escape the uncertainty of the political and religious uncertainty found in England, many English families boarded ships at great expense to sail for the colonies held by Britain. The passages were expensive, though, and the boats were unsafe, overcrowded, and ridden with disease. Those who were hardy and lucky enough to make the passage intact were rewarded with land, opportunity, and social environment less prone to religious and political persecution. Many of these families went on to be important contributors to the young nations of Canada and the United States where they settled. Tretheweys were some of the first of the immigrants to arrive in North America:
