Family

Francis I's first marriage was to Yolande of Anjou, daughter of Louis II of Anjou; they were married at Nantes in 1431. Francis and Yolande had a son, Renaud, Count of Montfort. Renaud died young and Yolande died in 1440.

His second marriage was to Isabel of Scotland (daughter of James I, King of Scots); he married Isabel at the Château d'Auray on 30 October 1442. Francis and Isabel had two daughters:

• Margaret of Brittany (1443–1469, Nantes), married Francis II, Duke of Brittany
• Marie of Brittany (1444–1506), married John II, Viscount of Rohan and Count of Porhoët.
