Hello everyone,
I’d like to present some research I’ve done recently attempting to prove overlapping royal lines to Henry III of England and Philip III of France for one of my ancestors, Claude de la Rôche du Ronzet, a captain in Colonial Mauritius. His line to Henry III of England is through the Dukes of Brittany, and both lines pass through Marguerite de Bretagne, an illegitimate daughter of OIivier de Blois, Comte de Penthièvre, and an unknown mistress. Many thanks to Peter Stewart for his response to my last post, which enabled me to find the original eight-page marriage contract between Marguerite and Brandelis de Caumont. For most of the intermediate generations I have relied almost exclusively on abstracts of original records contained in the ‘Cabinet des Titres’. I welcome any feedback on or critiques of my research.

Line to Charles of Valois:
1. Charles de Valois = Marguerite d’Anjou
2. Guy, Comte de Blois = Marguerite de Valois
That Marguerite, a Daughter of Charles de Valois and Sister to his Son Philip was to be married to Guy, a Son of Hughes, Comte de Blois, can be seen from their marriage contract dated October 1298. The date also proves that Marguerite was a daughter of Charles de Valois’ first wife, Marguerite d’Anjou, who died on 31 December 1299 according to her codicil:
