Alix de Savoie

From Medlands:

[ALIX de Savoie (-1277, bur Abbaye de Hautecombe). Guichenon names Alix as daughter of Comte Thomas I and his wife, stating that she was abbess of Saint-Pierre, Lyon in 1250, referring to "Titre de l´abbaye de Saint-Pierre de Lyon" with no precise citation reference[459]. The primary source which confirms her parentage has not yet been identified. She is not mentioned in the 11 Oct 1264 testament of her supposed brother Boniface Archbishop of Canterbury (which refers to his "sister the Ctss of Provence" and his "other sister the Ctss of Quibourc")[460], although this is not conclusive to dismiss her affiliation. One possibility is that Alix was the illegitimate daughter of Comte Thomas I.]
