The Scottish family of this name are stated to be a younger branch of the noble house of Seton. The ancestor is said to have fled into F ranee temp. James IV., in consequence of his having slain a gentleman in a sudden quarrel at a hunting match, and there to have adopted, for concealment, the name of Tytler. His two sons, bearing the same name, returned to Scotland with Queen Mary. B.L.G. The statement appears very improbable; and the etymology of the alias, if such it be, is unknown. Le Titteler occurs in H.R., and Jamieson, gives Titlar as a tattler, or talkative person.
