Westley is an English name derived from 'west', meaning 'from the west' or 'sunset'. It gained popularity in the U.S. post-William Goldman's novel 'The Princess Bride' (1973), featuring Westley as a heroic farmhand turned swordsman. Despite its recent rise, Westley remains relatively rare compared to other names like William or John. Its meaning and history reflect direction, adventure, love, and heroism.
