Per Laura Trevelyan, A Very British Family: The Trevelyans and Their World, London, 2006[1]: "The family coat of arms, which shows a white horse emerging from the sea with St Michael’s Mount behind.‘Time Trieth Troth’ is the motto. Family legend has it that upon the horse was a Trevelyan ancestor who escaped from Lyonesse, the mythical kingdom beyond Land’s End, while the knights in King Arthur’s court drowned. Doubts were cast on the legend of Lyonesse at the end of the nineteenth century, and it was somehow decided that this ‘first’ Trevelyan must have swum ashore on his horse for a wager".
