Avita Margaret of Savoy

There are ongoing doubts about Avoi. She is either the Illgt daughter of Thomas I or his son Thomas II. There were two profiles which represented these two positions in the tree but curators have decided that it is better to have only the one profile - d/o Thomas II.

B.date 1215 or 1245 don't seem supported by any source, paper, facts, probably just some sort of DIY calculation adaptation based on where someone wanted to place her.

18. [AVOIE [Marguerite] de Savoie (-shortly before 14 May 1292). Matthew of Paris reports that "Baldewinus de Ripariis, domina regina procurante, quondam alienigenam ducit in uxorem, Sabaudiensem, ipsius reginæ consanguineam"[483]. According to L'Art de vérifier les Dates[484], Avoie was the daughter of Thomasto I Comte de Savoie. The primary source which confirms her name has not yet been identified. It is argued in the Complete Peerage[485] that the wife of Baldwin de Reviers, 7th Earl of Devon, could not have been the daughter of Comte Thomas because she was referred to as 'Margaret' in other sources, Comte Thomas I's daughter of that name being the wife of Hartmann III Graf von Kyburg at the time of the Earl's marriage. The Complete Peerage[486] also refers to a writ on the Patent Roll of 52 Henry III "from which it appears that the king had given to the daughter [unnamed] of Thomas, sometime Count of Savoy, 500 marks on her marriage", this presumably being the widowed Countess of Devon on the occasion of her second marriage. The date of the writ matches the supposed second marriage of Avoie de Savoie. The Complete Peerage[487] assumes that the Count Thomas in question must have been Thomas II. However, the latter's second marriage (from which all his known surviving legitimate children were born) took place in 1251. This would exclude the Earl and Countess of Devon having a son "John who died an infant"[488]. The possibilities therefore seem to be (a) that the Countess of Devon was the illegitimate daughter of either Comte Thomas I or of Comte Thomas II; (b) that she was the legitimate daughter of Comte Thomas I, called either Avoie or Marguerite despite his having another legitimate daughter named Marguerite; or (c) that 'Thomas' in the Patent Roll writ was an error for another Count of Savoy (although it is unclear who this might have been as all other possibilities appear to be excluded). It is recognised that Avoie could not have been born much later than 1220 if she was the legitimate daughter of Comte Thomas I, and therefore would have been at least 17 years older than her first husband the Earl of Devon. Avoie is not mentioned in the 11 Oct 1264 will of her supposed brother Boniface Archbishop of Canterbury which made bequests to "sorori suæ comitissæ Provinciæ…sorori suæ alteræ comitissæ de Quiborc…"[489]. Although this omission is not conclusive as the testator's other presumed two sisters, abbesses Alix and Agathe, were not mentioned either, it is somewhat surprising that he would not have mentioned a legitimate sister who was then living in England, if he had one. The most likely probability is that Avoie was illegitimate. For presentation purposes in this document she is shown as the illegitimate daughter of Comte Thomas I, but it is recognised that Comte Thomas II is an alternative possible father.

m firstly (1257) BALDWIN de Reviers Earl of Devon, son of BALDWIN de Reviers Earl of Devon & his wife Amice de Clare (1 Jan 1236-in France 1262 before 13 Sep, bur Breamore Priory, Hampshire). [490]

m secondly (1269) as his second wife, Sir ROBERT Aguillon of Watton, Hertfordshire (-12 Feb 1286). Some details about the earlier history of the Aguillon family near Chartres are set out by the editor of the cartulary of Notre-Dame de Josaphat[491]. ]

There is some doubt about the paternity of Ctss Avoie. According to L'Art de vérifier les Dates, Avoie was the daughter of Thomas I Comte de Savoie. It is argued in the Complete Peerage that the wife of Baldwin de Reviers, 7th Earl of Devon, could not have been the daughter of Comte Thomas I because she was referred to as 'Margaret' in other sources, Comte Thomas I's daughter of that name being the wife of Hartmann III Gf von Kyburg at the time of the Earl's marriage. The Complete Peerage also refers to a writ on the Patent Roll of 52 Henry III 'from which it appears that the King had given to the daughter [unnamed] of Thomas, sometime Count of Savoy, 500 marks on her marriage', this presumably being the widowed Countess of Devon on her second marriage. The date of the writ matches the supposed second marriage of Avoie de Savoie, but the Complete Peerage assumes that the Count Thomas in question must have been Thomas II. However, the latter's second marriage (from which all his surviving legitimate children were born) took place in 1251. This would exclude the Earl and Countess of Devon having a son 'John who died an infant'. The possibilities therefore seem to be either (a) that the Countess of Devon was the illegitimate daughter of Comte Thomas II, (b) that she was the daughter of Thomas I called either Avoie or Marguerite (despite his having another daughter named Marguerite), or (c) that 'Thomas' in the Patent Roll writ was an error for another Count of Savoy (although it is unclear who this might have been as all the other possibilities appear to be excluded). It is recognised that Avoie could not have been born much later than 1220 if she was the daughter of Comte Thomas I, and therefore would have been at least 17 years older than her first husband the Earl of Devon. Avoie is not mentioned in the 14 Jan will 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"). Although this omission is not conclusive as the testator's other two sisters, abbesses Alix and Agathe, were not mentioned either, it is somewhat surprising that he would not have mentioned a sister who was living in England if he had one.
