The Chronicon Briocensi names "Conanum et Hazevisiam" as the two children of "Alanus filius primogenitus [Hoelli]" and his wife "Ermengardem filiam Comitis Andegavensis". The Genealogica Comitum Flandriæ Bertiniana refers to the wife of "Balduinum comitem" as "filiam Alani Fregani comitis Brittaniæ", but does not name her. The Flandria Generosa names "filiam Alani comitis Brittaniæ" as the wife of "Balduinus Inclitus", specifying that they were separated by Pope Pascal II on grounds of consanguinity. "Conanus…Britaniaæ dux cum sorore mea Hidevis et matre mea Ermeniart" donated property to the abbey of Sainte-Croix de Quimperlé by charter dated 1118, which names "pater meus Alanus et avus Hoel et attavus Alanus". "Mathilda comitissa et Haduisa soror comitis Conani" signed the undated charter Duke Conan III donated a fishery to the abbey of Mont-Saint-Michel. 1
