The name Layn is of American origin and has gained popularity in recent years. It is often considered a unisex name, although it is more commonly given to boys. Layn is believed to be derived from the English surname Layne, which is thought to have originated from Old English words meaning 'farm' or 'enclosure'. The name Layn is also sometimes associated with the Irish surname O'Leighin, which means 'descendant of Leighin', a personal name likely derived from a diminutive of the name Leith. However, these connections are not definitive, and the exact origin of the name Layn remains somewhat uncertain.
