Waltheri

Waltheri is a Latin genitive or Latinized form derived from the Old High German name Walther, composed of the elements wald, meaning rule or power, and hari, meaning army. The name belongs to the same Germanic family as Walter, Gauthier, and Gualtiero, all of which descend from the same two roots. It appears in medieval Latin texts and records as a scribal rendering of the vernacular Walther, reflecting the common practice of Latinizing Germanic personal names in ecclesiastical and administrative documents.
