Commentary
Charles Cawley: "The Inventory of the State Archives of Turin mentions a document dated 1230 which refers to the marriage of Comte Amédée with "Marguerite daughter of André dauphin, comte de Viennois", but without giving the context (marriage contract, appointment of proxy etc.). Although her mother is not named in this source, Marguerite must have been born from her father's first marriage given the estimated date of birth of her daughter Beatrix. The wife of Comte Amédée IV is named Marguerite de Bourgogne, daughter of Hugues III Duke of Burgundy [Capet] & his second wife Béatrix Dauphine de Viennois in the 18th century Histoire de Dauphiné but this appears to be disproved by the source referred to above."
