Arnoald, also called Arnoldus or Arnual (ca 560 – ca 611), was a Bishop of Metz between 601 and 609 or 611, the successor of Agilulf, and a Margrave of Schelde. He was the son of Ansbertus, a Senator, and wife Blithilde.
Married before 584 to Oda (?), born ca 564. Scholars looking to replace the traditions that would make Arnulf of Metz the son of Arnould have proposed alternative relationships between Arnoald and the Carolingians. Proposed solutions would make him father of one of the following:
It is a subject of much debate among genealogists whether or not Arnoald is the father of Arnulf bishop of Metz, who, according to Christian Settipani's early publications, is a perfect candidate. Settipani contradicts himself in newer publications, stating that Arnulf of Metz couldn't have been Arnoald's son given to no mention of the former having any royal blood. Further speculation indicate Arnulf's father could be a Bodegisel, based on documents from old Frankish legends. This statement is also uncertain. He states instead that Arnoald was Arnulf's father in law.
