GEOFFREY, DUKE OF BRITTANY, married Hawise, daughter of Richard I, DUKE OFNORMANDY, and died in 1008, leaving two sons, Alan and Eudon. During their mother's lifetime the two brothers seem to have been joint rulers of Brittany, but on her death, on 21 February 1034, dissensions broke out between them; peace was restored by a settlement under which Eudon received a territory corresponding roughly to the dioceses of Dol, St. Mialo, St. Brieuc and TrEguier, reduced in the hands of his successors to the two last-named dioceses, while Alan retained the rest of Brittany. After the death of Alan in 1040 Eudon seized the government of Brittany to the exclusion of his nephew Conan, who recovered it in 1057. Eudon died 7 January 1079. He married Orguen, whose parentage is unknown. [Complete Peerage X:779-81, (transcribed by Dave Utzinger)]
