The Artois Family were Junior Branch of the Frankish royal family, know as the Capets. The carpets were named after the first member of their dynasty. Hugh Capet Hugh was “elected ” because of his greater nobility— his messianic blood lines.
Blanche d’Artois Married both Edmund Crookback of England and Henry of Navarre. She had children —Juana Of Navarre , Thomas of Lancaster and Henry of Monmouth.
The Idea of carrying messianic blood went to Thomas’ head. he rebelled against Edward II and was eventually beheaded for his troubles.
Edward II married Isabella of France. It does not really matter who was Edward III’s father Isabella passed the same messianic line onto him. What the house of Lancaster pursued was not Edward’s possession of the messianic line but that if Roger Mortimer was his father then Edward III and his descendants had no right to the English throne.
Gaston, Comte de Foix, his wife Agnes of Navarre, Edward III and his Edward’s Lancaster cousins are all closely related.
Once again the d’Evreux family are a junior branch of the cadets.

She is important to the story as she becomes An important source of information for John and Ximene as they eventually begin negotiations with the Franks
Charles of Navarre
Phillipe’s son was Charles of Navarre who also Laid claim to the Frankish throne.
Charles claim also suffered from the fact that his descent was through a woman—Jeanne of Navarre— and perhaps fro the fact that there were some doubts about Jeanne’s Legitimacy .
Another glance at the geology of the Rois Maudites shows that the d’Evreux claim was virtually the same as that of the Valois, a small matter five years in birth date.
Agnes of Navarre
Phillipe’s younger daughter Agnes married Gaston (Phoebus) de Foix and is therefore Ximene’s aunt. Agnes is the initial catalyst for Ximene seeking assistance from Blanche d’Evreux.
