Lothar m
German: from an old Germanic personal name composed of the elements hlud fame + heri, hari army, warrior. St Lotharius was an 8th-century bishop of Séez in Orne, founder of the monastery of Saint-Loyer-des-Champs. Lothar was also a Frankish royal name in the Middle Ages, and was borne by two Holy Roman Emperors. Lothar I (795–855) gave his name to the province of LORRAINE (SEE Lorraine), which was all he was able to bequeath to his son (also called Lothar), after his quarrels with his brothers Charles the Bald and Louis the German. Lorraine (Latin Lotharingia, German Lothringen) was originally a much larger region than the present province.
Anglicized form: Lothair.
