Hawise of Normandy.
Hawise of Rennes (
Breton: Hawiz Breizh;
French: Havoise de Bretagne) (
c. 1024-1037 – 19 August 1072) was
Duchess of Brittany from 1066 until her death.
Hawise was daughter and heiress of
Alan III, Duke of Brittany, by his wife,
Bertha of Blois,[1] and as such, a member of the
House of Rennes. She had two siblings:
Conan II[2] and Emma of Brittany. Hawise succeeded her older brother Conan, who was assassinated by poisoning on 11 December 1066.[3]
Little is known of the life of Hawise of Rennes. She was married to
Hoel of Cornwall some time before 1058.[1] Hoel exercised authority jure uxoris and continued to control the government after her death in 1072 acting as regent for their son,
Alan IV.
