The Trevathan Surname Project


SUCCESSES SO FAR: - Proved that the descendants of William born 1690 are related to the descendants of John born 1780. - Determined that Trefethens in the U.S. are likely related to the Trevathans in the U.S. - Found that many Trevethans worldwide are not related to U.S. Trevathans. GOALS: - Find a Trevethan that is related to the U.S. Trevathans - Have more detailed testing done of U.S. Trevathans so that the exact relationship of John to William can be verified.
