Catherine of Artois

Catherine of Artois (1296–1368) was a daughter of Philip of Artois and Blanche of Brittany, and a sister of Robert III of Artois; her father died in 1298. Before 1320 she married John II of Ponthieu, Count of Aumale, and bore him two daughters.

Blanche, born in 1322, inherited Aumale and married John V of Harcourt between 1330 and 1340. Joan married John VI, Count of Vendôme, in April 1344 and later governed Vendôme for her infant granddaughter. John of Aumale died in January 1340, and Catherine outlived him by almost thirty years, dying in 1368.
