Mascarose II of Armagnac

Mascarose II (died 1254) ruled Armagnac and Fézensac as countess in her own right from 1246. The daughter of Arnaud Odon, Viscount of Lomagne, and Countess Mascarose I, she received the two counties from her father on her marriage to Eschivat de Chabanais.

Their cousin Géraud, Viscount of Fézensaguet, contested the succession, arguing the counties could not pass through women. She died childless in 1254, and Géraud succeeded as Géraud VI.
