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.

Trethewy migration to the United States +

To escape the political and religious chaos of this era, thousands of English families began to migrate to the New World in search of land and freedom from religious and political persecution. The passage was expensive and the ships were dark, crowded, and unsafe; however, those who made the voyage safely were encountered opportunities that were not available to them in their homeland. Many of the families that reached the New World at this time went on to make important contributions to the emerging nations of the United States and Canada. Research into various historical records has revealed some of first members of the Trethewy family to immigrate North America:

Emigration to New Zealand followed in the footsteps of the European explorers, such as Captain Cook (1769-70): first came sealers, whalers, missionaries, and traders. By 1838, the British New Zealand Company had begun buying land from the Maori tribes, and selling it to settlers, and, after the Treaty of Waitangi in 1840, many British families set out on the arduous six month journey from Britain to Aotearoa to start a new life.
