  Research Notes:

The Chronicon Briocensi names "Alanum, Mathiam et Benedictum" as the three children of "Hoellus…ex Hadevisa uxore sua". The Flandria Generosa names "comes Alanus" son of "Havisis Namnetensis comitissa", when outlining the basis for the consanguinity between his daughter Havise and her husband Baudouin VII Count of Flanders which constituted grounds for the couple's separation. "Constancius" donated property to the abbey of Redon with the consent of "Jedear uxore mea" and affirmed by "Hoel comes et Haduis comitissa, Alanus et Mathias et Eudo filii eorum" by charter dated before 1072. "Berta comitissa Alani Redonensis ducis uxor" donated property to Sainte-Croix de Quimperlé, for the souls of "filie nostre Hadeuis comitisse Hoelis ducis Britannie conjugis et…filiorum suorum, meorum…nepotum Alani et Mathie", by charter dated 1075, signed by "Alanus nothus filius Conani comitis, Vitalis et Gualterius Carnotenses, familiares comitisse Haduis neptis mee…".

He succeeded in 1084 as ALAIN IV "Fergant" Duke of Brittany. "Alanus comes filius Hoeli comitis" confirmed the rights of the abbey of Sainte-Croix de Quimperlé by charter dated 1084. "Alano qui et Fergant, Hoeli filio, totius Britannie consule" donated property to the abbey of Redon by charter dated 1092. He accompanied Robert III Duke of Normandy on the First Crusade. Albert of Aix names "…domnus Alens cognomine Fercans, Conans quoque, ambo principes Brittanorum…" among those who took part in the siege of Nikaia, dated to mid-1097 from the context.

He abdicated in [1114/16] in favour of his son, becoming a monk at the abbey of Redon: the Annals of St Salvator Redon record that "Alanus Fergent, ex Britonum duce rotonensis monachus, anno 1119 fato functus" was buried at the abbey of Redon. The Chronicon Britannico Alter records the death in 1119 of "Alanus Fergent pater Conani". The Chronicon Kemperlegiensis records the death "III Id Oct" in 1119 of "Alanus Fergant junior filius Hoëlis Comitis". 1
