• 1. JEAN de Bretagne ([1217/18]-Château de l'Isle, Férel, Morbihan 8 Oct 1286, bur Prières, église abbatiale de Notre Dame). The Chronicon Ruyensis Cœnobii records the birth in 1217 of "Johannes filius Petri Comitis et Aelidis Comitissæ Britanniæ"[359]. The Chronicon Britannicum records the birth in 1218 of "Johannes, filius Petri Ducis Britanniæ"[360]. He succeeded on the abdication of his father in 1237 as JEAN I "le Roux" Duke of Brittany.
• 2. YOLANDE de Bretagne (in Brittany end 1218-château de Bouteville 10 Oct 1272, bur Villeneuve-les-Nantes, église abbatiale de Notre Dame). A letter of King Henry III dated 19 Oct 1226 confirms his betrothal to "Jolentam filiam Petri ducis Brittanniæ et comitis Richemundiæ"[361]. The Chronicon Turonense records the betrothal of "Rex Franciæ Joannem fratrem suum, puerum octennem" and "filiæ Petri Comitis Britanniæ", and the grant of the county of Anjou to him[362]. The marriage contract between “P. dux Britannie, comes Richemondie…Yolendi filie mee” and “Ludovicus, rex Francorum…Johannem fratrem suum” is dated 27 Mar [1226/27][363]. The Annals of Dunstable record the betrothal of “filiam comitis Britanniæ” and “rex Franciæ…fratri suo minori”, who received the county of Anjou, in 1227[364]. Her betrothal to Thibaut IV Comte de Champagne is confirmed by a letter from King Louis IX to Comte Thibaut, dated 1229, which states that the king had “entendu que vous avez convenancé et promis à prendre à femme la fille du Comte Pierre de Bretaigne” and forbade him from proceeding, adding “la raison pourquoi vous savez bien” (without providing any further explanation)[365]. The 1229 date (cited by Lobineau) is presumably incorrect, assuming that the date of death of Comte Thibaut´s second wife is correctly reported as 11 Jul 1231 as shown above. This suggested redating is confirmed by a letter from Pope Gregory IX to the archbishop of Bourges dated 24 Apr 1232 stating that “Campaniæ et Britanniæ comites” intended to arrange a marriage alliance prohibited by the degrees of consanguinity and forbidding the arrangement[366]. Dame de la Fère-en-Tardenois, de Chailly et de Longjumeau. Ctss de Penthièvre 1236, as her dowry.

"Hugo Brunus comes Engolisme et domina Hiolendis uxor eius heres et domina Penthevrie" confirmed the donation to Lamballe made by “domini P. quondam ducis Britannie genitoris predicte Hiolendis uxoris nostre...domine Ælidis ducisse Britannie et comitisse Richem. genitricis predicte Hiolendis” by charter dated Jul 1247[369].

History from Wikipedia

Alix was born on or shortly before 5 September 1201. She was the daughter of Constance, Duchess of Brittany and Guy of Thouars. Constance died after giving birth to Alix and her twin sister Catherine. Alix's older half-brother was Arthur I, Duke of Brittany and her half-sister was Eleanor, Fair Maid of Brittany, the children of Constance and Geoffrey Plantagenet. Upon the death of Richard I of England, a power struggle commenced between her brother Arthur and King John of England. At the Battle of Mirebeau in 1202, Arthur and Eleanor were captured. Eleanor was imprisoned at Corfe Castle and her brother Arthur was murdered.

The Breton Barons recognized Alix as Duchess of Brittany after the death of her brother Arthur, instead her older sister, perhaps fearing John Lackland's claims to rule Brittany in representation of the imprisoned Eleanor's rights. Her father Guy became regent for Alix until 1206, when King Philip II of France made himself the regent of the Duchy in Alix’s name.

In 1213, the King arranged her marriage to his cousin Peter of Dreux, who became the regent. Alix died in childbirth, without having exercised much control over her own inheritance. She was succeeded in the Duchy by her son John I, but Peter remained the de facto ruler of Brittany until 1237.

Alix & Peter of Dreux had two surviving children

• John I, Duke of Brittany (1217-1286). Married 1236 Blanche of Navarre, whom he had issue.
• Yolande de Dreux, Countess of Penthièvre and of Porhoet (1218-10 October1272). Married January 1236 Hugh XI of Lusignan, Count of La Marche and Angouleme, by whom she had issue.
