Her parentage is unknown. She was a Suevian. On that basis, many assign her as a daughter of one Duke of Swabia or another.

The French Wikipedia page on Arnoald:

http://fr.wikipedia.org/wiki/Arnoald

casts some doubt about the name of Arnoald's wife being Oda:

La tradition lui attribue une épouse du nom d’Ode, mais c’est le résultat d’une confusion : au Moyen Âge, deux tradition à propos du père de saint Arnulf coexistaient, L’un donnaient Arnoald, l’autre donnait pour parent de saint Arnulf, Bodogisel et sainte Ode. Aegidius d’Orval a tenté de concilier les deux traditions en voulant faire d’Arnoald et de Bodogisel une personne unique[10]

In English:

Tradition attributes to Arnoald a wife named Oda, but this is the result of confusion in the middle ages, as two traditions about the father of St. Arnulf existed: in one, Arnoald is the parent, and in the other is a holy Bodogisel and Oda. Aegidius Orval attempts to reconcile the two traditions by making Arnoald and the Bodogisel a single person.

English Wikipedia page on Arnoald of Metz:

http://en.wikipedia.org/wiki/Arnoald

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:

Saint Itta, married to Pippin of Landen

Dode or Doda, who became a nun in 612 at Treves becoming called also Clothilde of Treves, born ca 584, married ca 596 to Arnulf of Metz

Father of St. Arnulf of Metz

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.

The 11th century life of her son Chlodulf names “mater…Chlodulfi Doda”[52]. Settipani states that this is the only source which names Arnulf´s wife, and inevitably casts doubt on the accuracy of the source written several centuries after she lived[53].

Arnulf & his wife had [three] children:

1. CHLODULF ([610]-8 May [697], bur Metz, basilique de Saint-Arnoul) m [CHILDA [Hilda], daughter of ---.
