The name comes from Luke Laux, the name of the evangelist. So he goes - as so many family names - on a first name (this name as a saint) back. Luke is two-syllable name was drawn together in everyday life to a monosyllabic names (contracts, say the linguists). Similarly, it is in Marx (from Markus), Frings (from Severin) and Krings (from Quirinus) be the case. The name Laux is mainly in the area of the Moselle and Eifel widespread, but in the Palatinate and Baden-Württemberg also indigenous . The same origin, the name Lux and Luke Luxem.Der market in Mayen / Eifel is popularly called Laux market.
