Originally a nickname for someone with red hair, occasionally used as a given name in the 20th century. As a girl's name it is sometimes a pet form of Virginia, as in the case of the film star Ginger Rogers (1911–1995, born Virginia McMath).
German: occupational name for a worker in iron, from Middle High German īsen ‘iron’ (see Eisen) + houwære, a derivative of houwen ‘to cut, chop, or hew’. As a vocabulary word, this is found in west central (Palatine) Germany only; elsewhere the standard term is Schmidt. In the United States, the Eisenhauers (and bearers of the various Americanized forms of the name) are found mainly in PA.
