• General Notes

  Both Turton and Leo van de Pas, citing ES, have Beatrice as daughter of William Montferrat, d. 1191, by Judith. However thepost below by Peter Stewart changes the classic ancestry.
  
  The following is excerpted from a post to SGM, 4 Feb 2003, by Peter Stewart:
  
  I think Tom was perhaps asking about the Beatrice who married Guigues V d'Albon, last male ruler of his line, becoming maternal grandmother to the first Burgundian Guigues d'Albonwhose (third?) wife, Beatrice de Montferrat, Sally mentioned.
  
  This earlier Beatrice is often named 'de Montferrat' too, but actually that was her mother's family. Her father was Alberto di Parodi, margrave of Gavi & her mother was Matilda de Montferrat. She married firstly ca 1155 Guigues V, dauphin of Viennois & count of Albon (died in July 1162) and secondly of Enrico, marquis of Caretto.
  
  Her daughter was another Beatrix, sometimes called la grande daupine (died 15 December 1228), who married first before 1179 Albric Taillefer, count of Saint-Gilles (died ca 1183); secondly in September 1183 (as his second wife) Hugues III, duke of Burgundy (died on crusade at Acre 25 August 1192) by whom she was ancestress of the later dauphins, including her son whom Sally had in mind; and thirdly in 1193 Hugues I, seigneur of Coligny-le-Neuf (died September 1205).
