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: 'Matuedoi comes' in Redon charters of 913-914 (Cartulaire de Redon nos. 275-277); in 913 he confirmed a gift 'quod rex Alanus antea atque Euuen nepos eius' had made to Redon - consistent with his being Alain the Great's son-in-law and successor in the west, but not a statement of it.
