  RESEARCH_NOTES: 1. “Royal Ancestry: A Study in Colonial & Medieval Families,” Douglas Richardson (2013): “EUDON OF BRITTANY, Count (or Duke) of Brittany, 2nd son. He married ORGUEN ___. They had eight sons, Geoffrey Boterel [I] [Count of Brittany], Alan the Red [Count of Brittany, lord of Richmond], Guillaume, Robert, Richard, Alan the Black [Count of Brittany, lord of Richmond], Brian [Count of Brittany], and Stephen or (Étienne) [Count of Brittany, lord of Richmond). By an unknown mistress (or mistresses), he also had four illegitimate sons, Bodin, Bardulf, Ribald, and Ernulf. During Their mother's lifetime, he and his older brother, Alan, seem to have been joint rulers of Brittany, but on her death in 1034, dissension broke out between them. Peace was restored by a settlement under which Eudon received a territory corresponding roughly to the dioceses of Dol, St. Malo, St. Brieuc, and Tréguier. After the death of Alan in 1140, Eudon seized the government of Brittany to the exclusion of Alan's son, Conan, who recovered it in 1057. His wife, Orguen, was living in 1056-60 (date of charter). EUDON OF BRITTANY died 7 Jan. 1079, and is said to have been buried in the Cathedral of St. Brieuc. Morice Histoire Ecclésiastique et Civil de Bretagne 1 (1750): xiii-xv (Counts of Cornouaille ped.)
