Arnaud I of Comminges

Arnaud I (c. 900–957) was count of Comminges and Couserans from about 940. Modern genealogists regard him as a son of Count Aznar III. He and his brother Roger I ruled the two counties jointly.

He appears with his wife Arsinde in donation charters to the abbeys of Lézat in 944 and Montolieu in 949. He died before 27 November 957, when a charter names only his widow and sons, and his lands were divided among his sons Roger, Eudes and Raymond.
