Hawise DE BRETAGNE , Duchess of Britany

  General Notes:

Hawise of Rennes (Breton: Hawiz Breizh; French: Havoise de Bretagne) (c. 1037 '96 19 August 1072) was hereditary Duchess of Brittany from 1066 until her death.

She was the second child and heiress of Alan III, Duke of Brittany, by his wife, Bertha of Blois, and as such, a member of the House of Rennes. Hawise succeeded her older brother, Conan II, who was assassinated by poisoning on 11 December 1066.[1]

Little is known of the life of Hawise of Rennes. She was married to Hoel of Cornwall some time before 1058. Hoel exercised authority jure uxoris and continued to control the government after her death in 1072 acting as regent for their son, Alan IV.

Hawise married Hoël II DE CORNOUAILLE Duke of Brittany, son of Alan DE CORNOUAILLE and Judith OF NANTES, before 1058. (Hoël II DE CORNOUAILLE Duke of Brittany was born about 1031 and died in 1084.)
