I am trying to find information regarding the family members of Rivallon de Dol-Combourg. Specifically his youngest son Geoffroi. Geoffroi is an enigma. What info written about him puts him in Mayenne with his descendants being the Seigneuries of Saint Berthevin La Tanniere, Levare, Ernee, Brece, Hemenare and Buron. I am unable to find any information as to whom he married. I am one of his descendants. Kathryn Keats-Rohan wrote some information regarding him and his connection as a member of the Rorgonides but nothing about whom he married.
If you have any information regarding Geoffroi I would appreciate it.
