Odo II had two children with Bertha: • Geoffrey de Porhoët • Adelaide (or Alix) of Porhoët (d. 1220). She was sent to
Henry II of England's court as a hostage and was alleged by his enemies to have become his mistress. This accusation remains unclear. She later became Abbess of
Fontevrault. Odo and his second wife had three or four children: • Odo III of Porhoët (died 1231). He was married, but the name of his wife is not known. • Harvey or Henry of Porhoët • Eleanor of Porhoët, wife of Conan of Penthièvre, de La Roche-Derrien, son of
Henry of Penthièvre, Count of Tréguier and Guingamp, and Mathilde de Vendôme. • maybe Alice of Porhoët, who married into the
Mauvoisin family ==Notes==
