The dukes had both a historical and ancestral connection to England and were also Earls of Richmond in Yorkshire. Duke Arthur II of Dreux married twice, first to Mary of Limoges (1260–1291), then to Yolande of Dreux, countess of Montfort (1263–1322) and widow of king Alexander III of Scotland. From his first marriage, he had three sons, including his heir John III and Guy, count of Penthièvre (d. 1331). From Yolande, Arthur had another son, John, who became count of Montfort.
