Arnau Mir

[1] The Memoria renovata, which dates to the reign of Raymond Berengar IV of Barcelona over the Kingdom of Aragon, contains a genealogy of Arnau Mir.

[2] In 1140, when William, Archbishop of Arles, acting as Papal legate, arbitrated the disputed boundary between the dioceses of Roda and Urgell, he did so "with the advice" (cum consilio) of Arnau Mir, who also signed the written agreement (convenientia) as a witness.

[3] Among the other magnates consulted for advice on this occasion were the Count of Pallars Sobirà, Artau III, and Arnau's vassal Ramon Pere II d'Erill.

[4] In Lleida and Agramunt Ramon accepted a pledge from Ermengol VI of Urgell which he did not repay.

It is recorded that one Berivizio wounded Pere de Castellnou, Arnau's liege vassal and nephew, and also murdered a man named Ros from Montanyana.
