Modern coinage, most common in North America. It is of unknown origin, probably a fanciful coinage based on Marlene or Charlene, or both. It became famous in the 1950s as the name of the American actress and beauty columnist Arlene Dahl (b. 1924).
Jewish (Ashkenazic): ornamental name from German Atlas or Polish atłas, both meaning ‘satin’ (ultimately from an Arabic word meaning ‘smooth’). It was probably also used as a metonymic occupational name for a merchant dealing in satin goods.
