Guy de Penthièvre

Guy de Bretagne, also Guy VII of Limoges (1287–1331), was the second son of Duke Arthur II of Brittany and Marie of Limoges. In 1314 his brother John III invested him with the viscounty of Limoges, but in 1317 the duke's wife Isabella recovered it, and Guy was compensated with the county of Penthièvre.

In 1318 he married Jeanne d'Avaugour; their daughter Jeanne de Penthièvre inherited his claims. He died suddenly on 27 March 1331 and was buried at Guingamp.
