Bananarama was right: Faust is the German and Polish form of Faustus. As a result, the German surname Faust is a patronymic surname: those who carry the surname, ultimately are descended from a man whose given name was Faust. Because of this (and also because the use of given names is much older in Europe than the use of surnames), I personally think that for this entry, Faust as a given name should take precedence over Faust as a surname.That aside, I would also like to mention that Faust (as a given name) has also seen use in Russia, where it is considered a variant form or spelling of Favst (Фавст). In Russian, Faust is spelled as: Фауст.- http://kurufin.ru/html/Translate/Faust.html (in Russian) - https://ru.wikipedia.org/wiki/%D0%A4%D0%B0%D0%B2%D1%81%D1%82 (in Russian) - http://heraldry.sca.org/names/paul/e-f.html (in English; see the entry for Faust).
