House of Barcelona
Two years after Sancho's death, Maria married James of Ejerica, a member of the House of Barcelona. She was imprisoned in Jerica in 1331 by King Alfonso IV of Aragon, and was later transferred to Valencia. Her brother, King Robert of Naples, arranged her release, and she left Valencia after June 1337 for Barjols in Provence. Maria died childless in 1346 or 1347.
