a French cardinal, was born at Montrelais, near Ancenis, about 1315. He early entered the service of the Church, and was made canon, and later archdeacon, of St. Peter's at Nantes. In 1354 he was elected bishop of Nantes, but the year after he was transferred by pope Innocent VI to the see of Treguier, and in 1358 to that of Sainte-Brienne. Devoted to Charles the Bald, Hugues accompanied that prince in 1364 to Poitiers to assist in diplomatic conferences. He also performed other diplomatic services. The troubles which agitated Brittany in 1371 caused Hugues's retirement to Avignon, where pope Gregory XI created him cardinal (December 20, 1375). He died there, February 28, 1384.
