the name of Eberhard's second wife is not recorded in contemporary primary sources, although Chestret de Haneffe notes that Le Fort said that she was "une comtesse de Looz", which could have been based on a genealogical table compiled by Pontus Heuterus (late 16th century) or on a monumental inscription recording the arms of her grandson Engelbert Seigneur de Loverval which quartered Mark with Looz[2210]. She is named "Maria (Gfn) von Looz" in Europäische Stammtafeln without specifying any precise parentage[2211].
