ALAIN (-907). Regino records that "Alanus frater Pasquitani" succeeded his brother, jointly with "Iudicheil, ex filia Herispoii regis natus"[73]. The Annales Mettenses names "Judicheil ex filia Heriospoii regis natus" when recording that he ruled jointly with "Alanus frater Pasquitani"[74]. He succeeded his brother in [876] as ALAIN I "le Grand" joint Duke of Brittany, ruling jointly with Judicaël son of Duke Gurwent. Regino records disputes between "Alanum et Iudicheil duces Brittonium" in 890[75] and, in an earlier passage, that Duke Alain ruled solely after Judicaël died fighting the Vikings[76]. The Anglo-Saxon Chronicle records that the Bretons defeated the Vikings at St Lo in 890 and "drove them into a river and drowned many"[77]. Guillaume of Jumièges records that Charles III "le Simple" King of the West Franks granted "terram maritimam ab Eptæ flumine usque ad Britannicos limites" together with "sua filia...Gisla" to Rollo who renounced his campaigns, that the king added "tota Britannia" and that “ipsius provinciæ principibus Berengerio atque Alanno” swore allegiance to Rollo[78]. The chronology of this passage appears incompatible with the death of Alain in 907. It appears that, after the death of Alain, power in Brittany was shared between the counts of Poher (Alain´s son-in-law), Vannes (Alain´s possible eldest son) and Cornouaïlle, and that none of them was acknowledged as overall ruler. It is likely that this situation persisted until the Viking invasion in 919 as no reference has been found to any overall Breton duke during that time in any of the primary sources so far consulted in the preparation of the present document. m [firstly] OREGUEN, daughter of ---. "Alanus…rex Brittaniæ" donated property "abbatial sancti Sergii in pago Andecavensi" to "Raino Andacavensis episcopus" to "episcopo Adalaldo archiepiscopo simulque Rainoni episcopo, fratri eiusdem" by charter dated [5 Feb 897/26 Nov 903], subscribed by "Orgaim uxoris suæ…Vuereche filii Alani, Pascuiten fratris sui"[79]. [m secondly as her first husband, ---. "Tanchi comes…cum…filiolum suum Derian, filium Alani" shared property which they donated to the abbey of Redon by charter dated 27 Nov 910, "Gurmahilon regnante Britanniam"[80]. This charter indicates that Tanguy was closely related to the family of Duke Alain. The use of the word "filiolus" suggests that Derien may have been Tanguy´s stepson. As Duke Alain´s other known children were adult by the late 9th century as shown by the various documents in which they are named, it is unlikely that their mother would have remarried after her husband´s death. The most likely explanation therefore is that Alain remarried after the death of his wife Oreguen, had a son by this second marriage, and that his widow married secondly Tanguy after her first husband died. This would explain the joint holding of property in which the other sons of Duke Alain are not stated to have held any interest.] Duke Alain I & his [first] wife had [six] children
