Mischling

(" mixed-blood" in German, plural: ) was the German term used during the Third Reich to denote persons deemed to have both Aryan and Jewish ancestry. The word has essentially the same origin as the 17th-century and now obsolete English term mestee, mestizo in Spanish and métis in French. In German, the word has the general denotation of hybrid, mongrel, or half-breed.
