Order of the Ermine
John IV, Duke of Brittany, founded the Order of the Ermine in 1381 after returning from exile in England. In 1448 it became the Order of the Ermine and the Ear of Grain.
Duchess Anne appointed Katherine Potier as an officer of arms after the death of her husband Yves. The order fell into disuse after Anne's daughter Claude died in 1524.
