Odo, Viscount of Porhoet

Who was Odo, Viscount of Porhoet?

Eudes/Odo II, Count of Porhoet was the son of Geoffroy, Vicomte de Porhoët, and his wife Hawise. He became Duke of Brittany in 1148 upon his marriage to Bertha, Duchess of Brittany, .

On Bertha's death, Odo II denied her son Conan IV of Penthièvre, Duke of Brittany his inheritance. While Odo II's marriage to Bertha was his first, it was her second marriage, her first being to Alain 'le Noir' de Penthièvre, Lord of Richmond. Odo II allied with his brother-in-law, Hoèl, Count of Nantes. Odo II was deposed by his stepson Conan IV in 1156, and taken prisoner by Conan IV's ally Raoul de Fougères.

A possible second marriage, in 1167, was to Jeanne/Eléonore de Léon, daughter of Guiomar III, Vicomte de Léon & his unnamed wife. Although Robert of Torigny records the marriage, he does not name her.
