Alan IV Fergant "Alan the Strong", Duke of Brittany, Count of Nantes and Rennes, from the Cornwall dynasty.
Son of Hoel de Cornuaille V, Count of Kernev and Duke of Brittany and Hawise de Bretagne, Duchess of Brittany. Grandson of Alain Cagniart Count de Cornuaille and Judith de Nantes, Alan III Duke of Brittany m Bertha of Chartres.
Alan married Constance, the favorite daughter of William the Conqueror in 1087, but they had no children by the time she died in 1090, supposedly poisoned.
Secondly, Alan married Ermengarde of Anjou, the only daughter of Count Fulk IV of Anjou and Hildegarde of Beaugency and previous wife of William of Aquitaine. They married in 1093 and had three children:
* Geoffrey, died young
* Conan, Duke of Brittany
* Hawise, wife of Count Baldwin VII of Flanders (some sources say Geoffrey de Porhoet Vicomte de Porhoet)
Alan was born into the war between William the Conqueror and his mother's brother, Conan II. To soothe the path for his invasion of England, William I married his favorite but unpopular in France (due to her "severe attitude" yet beloved by the Britons) daughter Constance to the Alan in 1087. William of Malmesbury believed Alan VI had Constance poisoned but nothing could be proven.
In 1092 Alan donated property to the abbey of Redon, and married Ermengarde of Anjou the following year as a political alliance with Fulk IV of Anjou. In 1098 Alan left on the First Crusade leaving Ermengarde as his regent, and returned in 1101.
Alan IV abdicated in 1112, and he and Ermengarde were separated as a result. Alan retired to the monastery of Redon, where he died in 1119.
