Mowbray

The House of Mowbray was an Anglo-Norman family named after Montbray in Normandy. Its English lands passed through Nigel d'Aubigny to his son Roger. A later William was among the twenty-five barons charged with enforcing Magna Carta in 1215.

A later Roger de Mowbray became the first Lord Mowbray under Edward I. His son John joined Lancaster's revolt and was captured at Boroughbridge and hanged at York in 1322; his marriage to a Braose heiress had brought Gower and Bramber. His son John was held in the Tower until 1327, served Edward III and died of plague in 1361.

Marriage to the Segrave heiress brought the earldom of Nottingham and the earl marshalship. In 1397 Richard II made Thomas Mowbray Duke of Norfolk. The direct line ended with the child Anne in 1481, and the Norfolk inheritance passed to the Howard family.
