John Archer Trevan moved to Port Isaac from the Plymouth area of Devon and he became a Customs Officer in 1793 and married Anne Watts in 1797. He inheritted the White House which was built in the reign of Queen Elizabeth by the Bosustowes family. It followed the female line into the Watts family and then the Trevan family. In 1912 it moved into the possession of the Hambly family, again following the female line.

Most of his offspring and their descendents stayed in the village. Most of the males became either Customs Officers or Doctors. Dr Frederick Trevan lived in Trevan House.

In the 1990's I spent a weekend staying at the Slipway Hotel, right opposite the harbour entrance. The White House can be seen in one of the photos on their site which looks at Port Isaac from the sea. It is on the right (west) of the harbour.

I have annotated the tithe map above to show the location of the properties in Port Isaac that have a Trevan connection, either through the tithe map itself, or in the survey done by Frederick's brother John Watts Trevan in c1833, or by a plaque above the door of Vesta House.
