Arnulf of Carinthia
Arnulf was the son of margrave Baldwin II of Flanders and Ælfthryth of Wessex, daughter of Alfred the Great. Through his mother he was a descendant of the Anglo-Saxon kings of England, and through his father, a descendant of Charlemagne. Presumably Arnulf was named either after Saint Arnulf of Metz, a progenitor of the Carolingian dynasty, or King Arnulf of Carinthia, whom his father supported.
