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

Early Origins of the Tretheway family

The surname Tretheway 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.

United States Tretheway migration to the United States +

For many English families, the social climate in England was oppressive and lacked opportunity for change. For such families, the shores of Ireland, Australia, and the New World beckoned. They left their homeland at great expense in ships that were overcrowded and full of disease. Many arrived after the long voyage sick, starving, and without a penny. But even those were greeted with greater opportunity than they could have experienced back home. Numerous English settlers who arrived in the United States and Canada at this time went on to make important contributions to the developing cultures of those countries. Many of those families went on to make significant contributions to the rapidly developing colonies in which they settled. Early North American records indicate many people bearing the name Tretheway were among those contributors:
