 The earlier notion that the village already existed in Roman times with the name "Martis Villa" ("Martis" being the genitive of "Mars", the war god, and thus this name would have meant “Mars’s Estate”) or "Villa Mercis" (“Warehouse Estate”) is not nowadays shared by regional historians.In Merzweiler, from the Middle Ages onwards, up to the late 16th century, stood a church.Whether the village was originally a self-administering parish is unknown.
