St Arnou

St. Arnou (also spelled Arnoul or Arnulf) refers primarily to one or more historical figures associated with the early medieval period, particularly within the Frankish kingdoms. The most prominent St. Arnou is likely:

• Arnulf of Metz (c. 582 – c. 640): A Frankish bishop of Metz and a major political figure in the Merovingian dynasty. He is considered a saint in the Roman Catholic Church and the Eastern Orthodox Church. Arnulf served as a court official under Theudebert II, King of Austrasia, eventually becoming bishop of Metz around 614. He played a significant role in the rise of the Carolingian dynasty, as he was an ancestor of Charlemagne. He retired to a hermitage late in life.

There are potentially other, lesser-known figures bearing similar names who have been venerated locally as saints. Any further individuals would require additional historical research for verification and distinct identification.
