Alain I the Great King of Brittany

✓ Alain I 'the Great' (le Grand), Count of Vannes, Duke of Brittany (d. 907), brother of Pascweten (Regino: 'Alanus frater Pasquitani'); ruled Brittany jointly from 876 with Judicael (grandson of Erispoe), then alone; defeated the Vikings 890 (the Anglo-Saxon Chronicle: drove them into a river and drowned many). STYLED KING: a charter after 5 Feb 897 runs 'Alanus rex, summus Britonnum dux'; a Redon charter of 913 speaks of 'rex Alanus'. Medieval Lands and most modern writers catalogue him as Duke. Parents not known; NOT a descendant of Nominoe, Erispoe or Salomon (his brother Pascweten married Salomon's daughter Prostlon, from whom nothing in this tree descends). TOP - nothing further wired. Source: Medieval Lands (fmg.ac, Cawley), 'Brittany Dukes' (Families of the Comtes de Poher and of Nantes) and 'Brittany Nobility - Nantes', read 2 Nov 2026; the filiations rest on the 11th-century Chronicle of Nantes (chronicle-only, hence ~). [DIRECT ANCESTOR OF THE COMPILER: flag added 2 Nov 2026 by walking the tree from Aynsley, so that this marker is reliable and can be searched.] ||2 Nov 2026 - EVIDENCE AUDIT|| PERSON attested: Regino and the Annales Mettenses (contemporary); Anglo-Saxon Chronicle 890; charters of Redon (897 'Alanus rex, summus Britonnum dux'; 'Signum piissimi ac misericordissimi Britonum regis, Alani' in a charter printed by Merlet; 913 'rex Alanus'). His sons Guerech, Pascweten, Budic, Rudalt and Derien are charter-attested; the daughter married to Mathuedoi is known only from the Chronicle of Nantes (see her note). Sources checked 2 Nov 2026: R. Merlet (ed.), La Chronique de Nantes (1896), text and notes; A. de La Borderie, Histoire de Bretagne II (1906); P. Lauer (ed.), Les Annales de Flodoard (1905), notes; Medieval Lands 'Brittany Dukes'. Not reachable: J. M. H. Smith, Province and Empire (1992) and Guillotel/Chedeville (lending-only or not online). ||2 Nov 2026 - UPGRADED TO ✓|| Person fully attested (annals and charters); his daughter's line to Alan II confirmed by Smith (1992). Source: Julia M. H. Smith, Province and Empire: Brittany and the Carolingians (Cambridge, 1992), Figure 2 'The rulers of Carolingian Brittany' (p. xvii: ALAN I = Oreguen; daughter = Matuedoe; ALAN II (Twistedbeard); 'Counts of Nantes'), p. 139 ('his grandson Alan II on reconquering Brittany ... in 936-7'), pp. 196-7 (Matuedoe, count of Poher, fled to Athelstan's court; Athelstan godfather to 'Matuedoe's infant son Alan II'); read 2 Nov 2026 from Aynsley's copy. Smith calls the Chronicle of Nantes 'a late compilation ... generally extremely unreliable' (p. 94 n. 27), yet gives this descent in her own voice. ||2 Nov 2026 - KING, NOT 'STYLED' (roll ruling, Aynsley)|| Reckoned the last King of the Bretons: charters 'Alanus rex, summus Britonnum dux' (after 897), 'Signum piissimi ac misericordissimi Britonum regis, Alani', 'rex Alanus' (913); La Borderie (Histoire de Bretagne II, 1906): 'Il fut le dernier roi des Bretons', the fourth after Nominoe, Erispoe and Salomon. Kernevez (2023): after him 'neither the royal Breton title nor Breton unity were reinstated' and Alain II Barbetorte 'gave up his claim to the royal title and only used that of Duke'. NAME field changed from 'Duke of Brittany' to 'King of Brittany'. Every rung from him to the compiler is ✓ (w93-w95). Supersedes the 'STYLED KING' wording above.
