Odo II, Viscount of Porhoët

Odo II, Count of Porhoet (died after 1180) was the son of Geoffroy, Viscount de Porhoët, and his wife Hawise (possibly Fergant). He became Duke of Brittany in 1148 upon his marriage to Bertha, Duchess of Brittany.[1]

On Bertha's death, Odo II denied her son Conan IV of Penthièvre, Duke of Brittany his inheritance.[2] 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 (Alan, 1st Earl of Richmond).[1] Odo II allied with his brother-in-law, Hoèl, Count of Nantes. Odo II was deposed by his stepson Conan IV in 1156,[1] and taken prisoner by Conan IV's ally Raoul de Fougères.

He married secondly, in 1167, to Alienor of Leon, daughter of Guihomar IV, Viscount of Léon and his wife Nobilis.[3]

Notes
  1. Everard states Eudo and Bertha had only one daughter, Adelaide.[5]
gollark: Wait, what would we actually find out?
gollark: Launch *us* or a probe? I vote yes for the probe.
gollark: We could start on the ~~giant lasers of death~~ solar power system of peace, though it seems that most of our stuff is self-powered anyway.
gollark: On the one hand, you can get more miners. On the other, they have to ship everything back, and coordination/control is a problem.
gollark: Come to think of it, it would make more sense to only have a few universal constructor factories and have them produce non-replicating miner probes.
