Berthe de Bretagne

  General Notes:

BERTHE de Bretagne (-[1158/64]). The Chronicon Britannico Alter records the death in 1148 of "Conanus Dux Britanniæ" and records that he had disinherited "Hoellus…suum…filium" and that he appointed as his successor "Eudone Vicecomite Porhoëtensi" who had married "sororem eius Bertam". Her first marriage is suggested by the Chronicon Kemperlegiensis which records the death in 1146 of "Alanus Niger, Conani Ducis gener". The primary source which confirms that it was Conan's daughter Berthe who married Alain has not yet been identified.
