Beatrice, di Montferrato

- https://en.wikipedia.org/wiki/Beatrice_of_Montferrat

Secondo alcuni cronisti, Beatrice dopo essere rimasta vedova si sposò in seconde nozze con Guido II, Signore di Bâgé, ma secondo la Histoire généalogique de la royale maison de Savoie è una errata interpretazione di un documento dove Beatrice viene citata, come Delfina (Beatrix de Montferrat veuve du Daufin André)[11].

4. BEATRICE di Monferrato ([1204/10][195]-after Mar 1276). The Aymari Rivalli De Allobrogibus records the marriage of "Andreas Delphinus" and "Beatricem, Guillermi marchionis Montisferrati filiam" after repudiating his first wife[196]. The testament of "Dom. Andreas Dalphinus Viennensis et Albonis comitis" is dated 4 Mar 1236, names as his heir "Guigonem filium suum", and appoints "Beatricem uxorem suam comitissam matris eiusdem Guigonis" as his tutor[197]. Many secondary sources state that Beatrice married, as her second husband, Guy [II] Seigneur de Bâgé (see BURGUNDY DUCHY NOBILITY). Guichenon, in his Histoire de Savoie, explains the background to this error, recording that "Pingon, du Buttet, du Chesne et les sainte Marthe…moi après eux" confused the name "Dauphine", under which Guy´s widow is recorded with the title "Dauphine [de Viennois]"[198], the widow of André Comte d´Albon being the only available person with that title.

m (21 Nov 1219) as his third wife, ANDRE de Bourgogne Comte de Gap et d'Embrun, son of HUGUES III Duke of Burgundy [Capet] & his second wife Béatrix de Viennois (1184-14 Mar 1237, bur Grenoble, église collégiale de Saint-André). He succeeded his mother in 1228 as Comte d'Albon, Dauphin.
