Guillemundus

Guillemó (died 827), also known as Guillemundus, was Count of Rasez and Conflent, son of Berà. He received these counties from delegation of his father (before 820) and retained them when Berà died in 820. In 826 he joined the revolt of Aysun or Aissó and, routed, fled to Córdoba.

The name Guillemundus was given him in honour of his great father Guillem (William) the Saint, count of Toulouse, cousin of Charlemagne, but with the ending "undus" probably by the influence of Guillem's wife Khunegunda.
