--- of Brittany (da. of Alain I)

✓ ---, daughter of Alain I 'the Great', Duke of Brittany: the Chronicle of Nantes records that the mother of Mathuedoi's son Alain (Barbetorte) was 'filia Alani Magni Britonum ducis'. Name not recorded; her mother (Alain I's first wife) not 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 - THE CRUX RUNG|| Only source: Chronicle of Nantes c. 27 ('ex filia Alani Magni, Britonum ducis'). No charter names her. Merlet: 'Alain eut en outre une fille qui epousa Mathuedoi, comte de Poher'; La Borderie, Lauer and Medieval Lands accept it without qualification. Indirect support: Mathuedoi confirming 'rex Alanus's' gift in 913. Whether this reaches ✓ depends on Aynsley's ruling (reference-work consensus over a single 11th-century chronicle). 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 ✓|| Crux rung now meets reference-work consensus: Smith (1992) draws her as Alan I's daughter, wife of Matuedoe and mother of Alan II, and calls Alan II Alan I's grandson in her own text; Merlet, La Borderie, Lauer and Medieval Lands agree. Smith's table places all of Alan I's children under 'ALAN I = Oreguen'; Merlet and Medieval Lands leave the daughter's mother open - Oreguen NOT wired. 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 - FURTHER CONFIRMATION|| Kernevez (2023): 'Mathuedoi, count of Poher and the son-in-law of Alan the Great'.
