Anglicized form of the Irish name Dubhán or of the surname (Ó Dubháin) derived from it. Its popularity in the English-speaking world in the mid-1950s was influenced by the U.S. guitarist Duane Eddy (b. 1938).
English (of Norman origin): nickname for a crafty or ingenious person, from a reduced form of Old French engaine ‘ingenuity’, ‘trickery’ (Latin ingenium ‘native wit’). The word was also used in a concrete sense of a stratagem or device, particularly a trap.
