The families of Castile
In Europe in 1350 there was a belief that the family of Ximene’ grandmother (de Padilla) had a matrilineal descent from Jesus. This is the reason that the sons of Edward III married illegitimate Daughters of Pedro (the Cruel) of Seville. However if that holy blood flowed through the veins of the Perez sisters, then it also flowed through to Ximene. This was the reason that the Black Prince took such great risks to meet Ximene and negotiate a marriage contract with her.
