I have a book called "Tregears around the World" which is pretty complete and traces three families of Tregear from about 1600: Keverne Tregear, John Tregear and Phillip Tregear. They all started out in St Just and Sanscreed. Would you have any other names? The Thomasin is nice and unusual but I don't have one. Do you have any other names and times (preferably not Ann and John Tregear) ?
