Originally a medieval French diminutive form of Marie, introduced to Britain in the Middle Ages. In some places it was taken as a pet form of Margaret or Margery. As a male name, it is an altered form of the Continental male name Marian, a derivative of Latin Marianus (from Marius), but is now rarely, if ever, used. It was the birth name of the American film star John Wayne (1907–79).
English and Dutch: occupational name for a tanner of skins, Middle English tanner, Middle Dutch taenre. (The Middle English form derives from Old English tannere, from Late Latin tannarius, reinforced by Old French taneor, from Late Latin tannator; both Late Latin forms derive from a verb tannare, possibly from a Celtic word for the oak, whose bark was used in the process.)
